Hi,
I have issue that when i try to download in frontend the attach file its give error 500 :

"The kwt.education page isn’t working

kwt.education is currently unable to handle this request.
HTTP ERROR 500"

But when i try to download from backend the file is download with no issue.

This issue start suddenly and before i can download any attachment, almost i don't modified any thing with my website.
I try to turn off Joomla SEF and the issue also not solve it.

Hello,

500 is a generic error, can you enable error reporting and set it development (global configuration options) to see the actual issue?

Hi Krikor,
Thanks for your response
This the error

Fatal error: Cannot redeclare class K2ModelItem in /public_html/administrator/components/com_k2/models/item.php on line 1375

Hello,
Check if there is any K2 plugin enabled that might be responsible for this conflict.

Hi Teo,
i disable the plugin but still the issue not fix

Can you provide a list with all the K2 type plugins installed at your site ?

Hi Teo,
Sure :
1-Smart Search - K2 (Disabled)
2-Josetta - K2 Categories (Enabled)
3-Josetta - K2 Items (Enabled)
4-Open Graph - K2 (Disabled)
5-Search - K2 (Enabled)
6-Social Profiles - K2 (Disabled)
7-System - Widgetkit K2 (Enabled)
8-System - K2 (Enabled)
9-User - K2 (Enabled)

My Joomla is 3.4

I try to disable all except "System - K2" and not fix the issue
