Hello,

A Deprecated notice will not affect your site's functionality in any way.
Look in your error_log for any Fatal errors.

same Problem here...
I get this error after saving an Item:
Fatal error: Cannot declare class upload, because the name is already in use in /ROOT/administrator/components/com_k2/lib/class.upload.php on line 624

this error appears only, if the plugin is active. the errormessage it's not related to K2 itself

and some other warnings like this:
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; plgK2Png4k2 has a deprecated constructor in /ROOT/plugins/k2/png4k2/png4k2.php on line 16

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; upload has a deprecated constructor in /ROOT/administrator/components/com_k2/lib/class.upload.php on line 624

Hello.

Like others, I fell victim to the 3.8 update problems.
I have spent the last week trying to get a functional site back up and running.
While I'm still dealing with Community Builder, most things appear fixed with my other plugins and add-ons.

However, when I went in to edit one of my K2 article in the back-end admin section, I get a completely blank white page.
The previous articles all show fine. If I try to create a new article, same thing - white page.

Error shows as:

Fatal error: Call to undefined method WFFileBrowser::getInstance() in /home3/fulltang/public_html/kimstkdojang/components/com_jce/editor/libraries/classes/manager.php on line 62

I have the most current version of K2 installed.

Assistance would be appreciated.
Thank you for any and all help.

Is there something wrong with his code?

The only other thing I was running that had anything to do with k2 was Simple Gallery made by you guys. There is nothing else associated to k2. I turned it off, but still get the error.

Same problem for me. When I try to save a k2 item, I get a blank page. I see this error in log after trying:

2017-08-30 10:38:24.338 [NOTICE] [xx.x.xxx.xx:63660:HTTP2-25] [STDERR] PHP Fatal error: Cannot redeclare class upload in /home/xxx/domains/xxxxxxxxx.xx/private_html/administrator/components/com_k2/lib/class.upload.php on line 624

Se qualcuno si è già imbattuto nel problema ed è così gentile da aiutarmi
Grazie in anticipo

I had today the same issue, but i'm using JoomlaVi Latest News Module.
After upgrading k2 to 2.8, I can no longer edit this module.

Fatal error: Call to undefined method K2HelperHTML::loadjQuery() in C:\wamp64\www\camajussite2\administrator\components\com_k2\elements\items.php on line 29

I'm using:
Joomla 3.64
K2 2.8
PHP 5.6

Yes, the culprit was found :)
Report this issue to the K2 Multi Image devs so they can provide a solution and a possible update.

Hi,

Thanks for following up on this.

I'm wondering if my upgrade went bad or something, since I still had these files in my structure, despite upgrading from the Joomla Extensions/manage/Update route.

I've now downloaded the 2.8 zip & installed that over K2 using Extensions/manage/Install route.

K2 now says it's running 2.8 -> (Last update: August 18th, 2017 - Version 2.8.0)

However, I'm still getting fatal errors on save:

Warning: require_once(/home/.../public_html/administrator/components/com_k2/lib/class.upload.php): failed to open stream: No such file or directory in /home/..../public_html/plugins/system/k2multiimages/K2MultiImages/administrator/models/itemmultiimages.php on line 5

Fatal error: require_once(): Failed opening required '/home/.../public_html/administrator/components/com_k2/lib/class.upload.php' (include_path='.:/usr/local/php70/pear') in /home/.../public_html/plugins/system/k2multiimages/K2MultiImages/administrator/models/itemmultiimages.php on line 5

However, disabling the k2multiimages plugin allows me to save items. Perhaps this extension needs updating to account for the removal of class.upload.php from the lib folder?

Thanks again for your assistance - much appreciated.

Regards,
Eddie

As you can see -> github.com/getk2/k2/tree/master/components/com_k2 the /lib/ folder is not present in the 2.8.x version.

Try renaming that folder and see if the error is gone. Better yet clear all caches and reinstall 2.8 before performing any tasks.

Hi,
There is another instance of class.upload.php in /media/k2/assets/vendors/verot/class.upload.php/src/
Removing the directory leads to another fatal error - missing the verot version of class.upload.php

This issue has only arisen since updating K2 to 2.8. The verot class was updated as part of the k2 2.8 upgrade.

Kind regards,

As the original error indicates, there is already another instance of class.upload.php being loaded first, causing issues in K2. As for the warnings you get, just switch error reporting to none or default in Global Configuration.

Hi,
Disabled mefgfork2 - error msgs disappeared when editing a category.

However, still can't edit a K2 item:
Fatal error: Cannot declare class upload, because the name is already in use in /home/.../public_html/administrator/components/com_k2/lib/class.upload.php on line 624

Cheers,

These are coming from a 3rd party K2 extension.
Try disabling this extension (mefgfork2) as well.

K2 will not inject styling on 3rd party modules.
This is a PHP error. Look in your error_log for any Fatal Errors in order to find the culprit.

Sorry,
2 more warnings when editing K2 category:

Warning: Declaration of K2ElementMultiSelects::render() should be compatible with K2Element::render($layoutId, $data = Array) in /home/.../public_html/plugins/k2/mefgfork2/elements/multiselects.php on line 0

Warning: Declaration of K2ElementImages::render() should be compatible with K2Element::render($layoutId, $data = Array) in /home/.../public_html/plugins/k2/mefgfork2/elements/images.php on line 0

Cheers,

I cannot verify this issue, nor has it been reported by other users using 2.8 or 2.8 DEV. Is this issue present in other sites as well?

Hi,

Looking at K2 categories I get the following warning:

Warning: Declaration of K2ElementExtraFieldGroups::render() should be compatible with K2Element::render($layoutId, $data = Array) in /home/..../public_html/plugins/k2/mefgfork2/elements/extrafieldgroups.php on line 14
