i updated jomsocial today and now if i click on backend to jomsocial i get this error
"Fatal error: Cannot redeclare class CommunityModelPhotos in /homepages/....root...../components/com_community/models/photos.php on line 18

Hello,
thank you but i know about 500 Errors and this isnt.

it wrote i have backend error on jomsocial component so please can anybody help me.?

Hi there.

Your back-end access does't seems to be valid, could you check it once again?

Have done!

I dont know why but always if i enter backend Access on your Forum and saving then it saves the http link 2 Times. This is why the Access is invalid. I have changed now

Hi Marco.

This problem was also happening on Joomla 3.2.0 version ?

cant say sure..
What could the error cause?

I'm still not really sure, I saw this error on couple of other sites so I'm still looking for a cause of this issue.

Is it possible that is something with this

plugins/system/azrul.system/pc_includes/ajax_1.5.pack.js ? Ans it makes some conflict with other plugins?

I looked again, but can find nothing.
CommunityModelPhotos this is load double times i think right devvers? But i dont know where you have to look. I think it is not jomsocial, but a plugin who is meesing up some code

forgive me if i am wrong, i only like to help.

Hm...to track this extension you may try this solution > Since it looks like an javascript conflict I suggest to set your site under maintenance mode, and try to disable all extensions exept of those listed below, in such way you should be able to track this problematic extension. You can also try to download whole page on your hdd and create an copy of it on some dev domain, and there disable all extensions.
