Fatal error: Cannot make static method JLoader::import() non static in class PhocaGalleryLoader in /.../administrator/components/com_phocagallery/libraries/loader.php on line 75
I looked at:

But I still don't know what to do?
How to find the component who has changed the core file?
Please help me to find the answer!
joomla 2.5
Good day!

Hi, first use 3.2.5, second, seems like you have some problems with the site (e.g. the files are not copied, problem with permissions, etc.) Try to recheck your ftp settings and be sure, uploaded or installed files are correctly stored on your server.
