I cant see front end and cant get in to back end as there is no log in only this error message. I have been told by my host to contact you on how to deal with getting back my backend log in screen so I can log in and apparently I have to update K2 module or something. Thank you. Please assist as I have had 5 clients already ask what is happenning to my site

It sounds like an issue with the extension. It probably does not support K2.

You can try disabling the Enable K2 User Profile setting in K2's advanced settings.

The Facebook extension is www.oneall.com/

K2 is K2 v2.6.8

With the firewall disabled I still have the same issue. It says for a second you are logged in with Facebook then goes to the error page. I t does register you on the back end though.

Which extension are you using to log from FB?
Also which version of K2 are you using?
If you disable the Firewall are you able to login?

Sorry I forgot to mention that the error

"Fatal error: Class 'K2Table' not found in /homepages/12/d51035808/htdocs/xxxxxxxxxx.com/administrator/components/com_k2/tables/k2user.php on line 14"

comes up when I log in with Facebook, oddly enough the account is created on the back end nevertheless.

Thanks for the quick response. I tried deactivating Captcha and nothing changed. I am using DMC Firewall

Are you using any other extensions? Are your captcha setting properly configured or are you using any security extensions?

Also when I try to create a user profile from the front end I get:


Incorrect Code

Please help, I have the same problem too, whenever a visitor tries to register.

Can you helpme?

Hi, just wondering if there is anymore progress on this topic. I am getting the exact same error. And yes the Joomla version is 1.5.6 and k2 is version 2.6.8. The errors are exactly as reported previously, and here:

Warning: require_once(/home/win24co/public_html/components/com_mailto/helpers/mailto.php) [function.require-once]: failed to open stream: No such file or directory in /home/win24co/public_html/components/com_k2/views/item/view.html.php on line 403

Fatal error: require_once() [function.require]: Failed opening required '/home/win24co/public_html/components/com_mailto/helpers/mailto.php' (include_path='.:/opt/alt/php52/usr/share/pear:/opt/alt/php52/usr/share/php') in /home/win24co/public_html/components/com_k2/views/item/view.html.php on line 403

K2 version is written in the footer in K2 administration pages. Joomla! version can be seen at the system information page.

Olá ...
Ao inserir article pelo k2 e usar a aba de galeria de imagens, tendo instalado o plugin simple-image-gallery-pro, tenho o seguinte erro no servidor...

PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 3543 bytes) in /var/www/html/portal/plugins/content/jw_sigpro/jw_sigpro/includes/helper.php on line 266

São 2(duas) imagens compactadas, uma de 8,9mb e outra de 13,4mb.
No php.ini tenho as variáveis (max_file_uploads 50) e (upload_max_filesize 230MB / max_size_upload 230mb) ...

Também na configuração (parâmetros) do k2 na aba imagem tem a opção:
" Impor limite de memória (em MBs) para processamento de imagens " e também coloquei 230MB.

O que mais pode ter que não libera o upload dessas imagens?

Obrigado,


Hello ...
By inserting article by k2 and use the tab gallery, having installed the simple-image-gallery-pro plugin, I have the following error in the server ...

PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 3543 bytes) in /var/www/html/portal/plugins/content/jw_sigpro/jw_sigpro/includes/helper.php on line 266

Are two (2) compressed images, one of 8,9mb and another 13,4mb.
In php.ini I have the variables (max_file_uploads 50) and (upload_max_filesize 230MB / 230MB max_size_upload) ...

Also in the configuration (parameters) of k2 tab image has the option:

What else can not have it releases uploading these pictures?

Thank you,

Are there any Fatal Errors in your error_log?
Even if they seem unrelated to the issue.
