I am having the same problem

I just upgraded one of my sites to K2 v 2.3

The K2 articles do not load now. I am also unable to add an article from the backend - blank page when clicking "save"

Site in question: www.hobnobmaster.com

I rolled the site back to it's previous state (K2 V 2.2) and recorded a one minute screencast showing the upgrade to V 2.3 and the subsequent blank page that results

I do have PHP's "GD Image Library" installed

Hi,I was using K2 version 2.2. I then upgraded to 2.3. On 2.2 the text would show up next to the images and would not get pulled down to the bottom of the image. Now with 2.3 if i have an image in an article, then the text starts at the bottom of the image. 

You can see what i am talking about at www.picooze.com/joomla
Could you kindly help me fix this problem.

Paulette Marzahl said:I would like to know this process as well, since I keep getting an error when trying to upgrade.

Thanks for responding, Erik. reinstalling the site is not an option. This has me concerned, as I've been installing K2 on all my sites. If it's going to cause errors such as the above, it's definitely a serious issue. I'm sure if I uninstall K2 2.2, I will lose all my items and categories - right? I've also modified the k2.css file.

Erik Prestinary said:hello paullette
i had a very similar issue. I ended up reinstalling the whole template and the site.

Regards!

I finally did:

1- backup to jos_k2_*** tables in phpmyadmin
2- backup media/k2 folder in ftp
3- removed k2 v2.2
4- installed k2 v2.3
5- restored sql backup from point 1 (restored the original jos_k2_*** tables)
6- removed .txt from each media/k2/attachtments file (you can do this in your pc with a multiple renamer software)
7- uploaded k2 folder to media/k2 in ftp (overwrote everything)
8- removed .txt manually from each record in the jos_k2_attachtments table

It is a long and kinda complicated process, but I guess it is working fine now
PS: Software still shows v.2.2 in the control panel... I guess we'll have to do another upgrade soon


Vassilis said:Hi Lefteris, i still have teh same problem.
In every K2 site i create.
From every browser and with the latest version...
Any solution plz?

Lefteris Kavadas said:Hi. This is a mime detection problem. It seems that the class.upload.php fails to detect the correct mime type on your system. You can try: 1. Update K2 to it's latest version. It also updates the specific class to it's latest version. 2. Upload the file from a different browser.

Hey Daniel. Yes, this did the trick. Thanks for finding the bug. I hope that the fix is incorporated into a later release so that we don't have to 'fix' this issue every time. Thanks so much for finding the fix.

Daniel Kling said:just found the bug: in /modules/mod_k2_tools/helper.php on line 103 have to be a space before "ORDER" ... now the archive works
change
$query .= "ORDER BY created DESC";
to
$query .= " ORDER BY created DESC";

I know the answer might be found in this site. But this problem still exist after I upgraded to v2.3, so I would like to explain my situation and ask again.The situation is:I upgraded both my K2 site into K2 v2.3, thenSite A, which is still Joomla 1.5.15 (at hosting service A)  lightbox works perfect,Site B, which is Joomla 1.5.18 (at hosting service B)  lightbox didn't work well such as  **nothing happened when I click cancel or save button, which means the button didn't work  **extra field didn't change to related fields what it should be when I changed the categoryI tried to disable all other jQuery, mootool moudules at the same page, but the problem still not being solved.I don't understand what's the problem. Why lightbox can work perfectly in a site, but not well in another?  The only difference I can tell here is hosting space. But does this influence the performance of K2?So, anybody can help me to solve this problem at site B?

So, does some kind soul want to educate me and tell me how [ step by step, bit of an MS-type thing with achy fingers etc ]to do all this simple stuff.where do I find this K" to download it in the first place and is there a tutorial please.

Alexey said:In the parameters I can not remove or move using drag and drop any categories. Also, I can not add new users in the field "content source". It happened after I upgraded to version 2.3Tony Langham said:I've already created 207 categories and being basic learner [ and having good / bad days with MS ] would you be kind enough to enlarge on this pleaseJoomlaWorks said:Install K2, create your category structure in K2, create menu links to these K2 categories, then start adding articles to each category. Simple...

After a straight upgrade from 2.2 to 2.3 everything seems to work except the Archive (k2_tools) module has completely disappeared. It's enabled and positioned on the right on the blog page, as it was prior to the upgrade, but it does not show at all. If I change to Calendar the Calendar shows fine with the blog category selected. When I change it back to 'Archive' the module again does not show at all.I won't be able to upgrade to 2.3 until a resolution to this issue is found.Thanks Joomlaworks.

Enrique, thanks for the warning. Since I am still only testing v 2.3 locally in a very limited way without attachments or other extras, I have not experienced the other problem you describe, but it's obvious that I must check the upgrade very thoroughly before I install it on my production site. If I find anything that may be helpful to you I will post that at the other thread.

any1 plz?

Some extensions/plugins are designed to work with K2, others are not. You will have to search the exensions directory under with "k2" to find the ones that will see k2 items, and watch for yours to be upgraded. Mabee asking the publisher to upgrade would be good also

HiI've been trying to upgrade from 2.2 to 2.3Everything goes ok, I browse the file, click upload & install button, and then I get this message:

All installs fine, but when I load K2 from Components Menu, it still shows 2.2, like the upgrade didn't upgrade anything at all. Check the following image at bottom

Is there some way to update files manually to FTP?Thanks

Hello Erik,

I had the same problem upgrading to 2.3. But I tried to upgrade in two differents joomla installations, one in the root and the other in a directory. I don't have problems with the installation on the root. But I still have the problem with the installation in the directory.

HiI've upgraded to latest K2 (2.3)I had previously some 50 articles which contained attachtments. Some user noticed before that the attachtments were being uploaded and renamed automatically to .txt(See this community.getk2.org/xn/detail/3536014:Comment:64032)Once upgraded, I was told to delete all the attachtments from articles, and reupload again. Now when I try (with all the browsers) to delete any attachtment from the old articles, I get a blank page. I tried from backend and from frontend, with same result...This is the url that is being called: index.php?option=com_k2&view=item&task=deleteAttachment&id=9&cid=23How should I delete manually files from ftp and from mySQL table? And also, any way to fix this blank screen?ThanksPS: had no trouble when upgrading, no erros, no warnings
