I received the following error message after downloading the site files to a new domain name on the same server
Catchable fatal error: Argument 1 passed to RokSprocket_PlatformHelper_Joomla::processItemsForEvents() must be an instance of RokSprocket_ItemCollection, null given, called in /home/content/s/h/e/shebby/html/flotours/modules/mod_roksprocket/lib/ModRokSprocket.php on line 37 and defined in /home/content/s/h/e/shebby/html/flotours/components/com_roksprocket/lib/RokSprocket/PlatformHelper/Joomla.php on line 61
Which php version do you have on both servers? Try to set error reporting in joomla global config to the lowest level. Also, try to install latest version of RokSprocket
I'm having the same issue. Site was working on my local development server, but isn't working now that I've uploaded it to a remote server. I installed Admin tools and ran the "fix permissions" function—no luck. I get a screen with the error message. When I disable all RokSprocket modules, the site works. Any ideas?
Error is :
Catchable fatal error: Argument 1 passed to RokSprocket_PlatformHelper_Joomla::processItemsForEvents() must be an instance of RokSprocket_ItemCollection, null given, called in /home/local341/public_html/modules/mod_roksprocket/lib/ModRokSprocket.php on line 37 and defined in /home/local341/public_html/components/com_roksprocket/lib/RokSprocket/PlatformHelper/Joomla.php on line 69
Update.
I removed a css3 text-shadow from and element on the page and it seems to be working now. I have no idea what the connection is, but that seemed to do it.
