[Perms or Owner] Server Err on RSS, Flexicontent Templates

Hello,

I've cloned my Joomla 1.5 website with Akeeba Backup in order to update Flexicontent on my dev site before update the prod one.

After the upgrade, I can't access to any RSS feed, it must be a configuration problem, I'll fix this later. But after creating a multiple categories menu item and try to duplicate a Flexicontent Template, there is no way to go back to the Flexicontent template page, Server error too, and on my entire website too... When I check what's happened with FTP, nothing changed, even in flexicontent template folder...

Do you know what could happen ? Is this because it's a cloned website (on a directory) ?

My website : www.clape-media.com/akeeba-rb

Thanks

EDIT : FLEXIcontent version 2.0.2 r1680 & fr-FR.com_flexicontent.zip v1.5.6+

Hello

if template is not duplicate then permission of parent folder "template" must be wrong


About the blank page,
this is a usually PHP fatal error and we need to get it to appear

For this purpose, please go to Joomla 's Global configuration and set "Error reporting" to "simple" then visit frontend page to see if the PHP error appears

Permissions for template were to 777, but I've changed the error reporting to simple and it returns this :

When I check on my FTP, line 2529 is this :

Hello

both problem comes due to either permission problem or wrong ownership (please check this when restoring with Akeeaba Backup)

Two cases:
1. "denying" permissions for any PARENT folder up to the root (yes any parent folder up to the root)
e.g. if your folder is 777 but some parent folder is 444 then 444 takes effect

2. wrong ownership of created folders

yes even if folder is 777 a wrong owner will cause problems

this is because the sub-folders will be created with 744 permissions, again with wrong owner thus the 744 of the sub-folder will make files impossible to copy

Thanks for your help ! I've "chmoded" to 777 and owned the entire website but still not working... Is there any other possible cause to this ?

I've checked on every folder on my website, everything is set to 777.

Hello
is the owner of the folder/files same as the unix account that of the domain ?
