Warning: array_merge()

I'm getting this error :

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /home1/XXXXX/public_html/inc/classes/BxDolMemberMenu.php on line 517

This is what happen. I was having problems uploading and embeding video, I kept getting " Video upload failed (Video error) ". I suspected the problem was do to the video migration form 6.1 because everything worked fine before that. So I decided to reinstall a pre-migration backup Cleared the DB then I imported the backup database. I deleted all the site files and then re-uploaded the backup files.

The site came back online with no errors, until I logged in.  I  have no icons in the bottom menu, It's just blank. I cant access the Administration panel from the site. I can only get to it by URL/administration.

Line 517 is in the function createMemberMenuCache($sMenuSection)  It appears to be some kind of issue with " sMenuCacheFile "

How do I fix this problem?

Via cpanel or ftp  delete everything in public_cache  and cache folder.  Leave .htaccess in Cache folder  DO NOT DELETE IT .

See what happens after that.  chances are you carried over the cache from the move maybe.

Problem has been resolved thanks to Zarcon's post: http://www.boonex.com/unity/forums/#topic/Making-Changes-Clear-Your-Cache-.htm

dolphin_jay Thanks, I just cleared the contents of the cache folder. Now I'm going to clear public_cache folder also.

ok cool
