[RESOLVED] Site Down -- Cause unknown. Please help!!!#

Hey guys,

I've just been advised that a Revo-powered site I developed has crashed for a reason unknown at this point.

I get the following error when i load the home page or the manager or any other page for that matter:

Warning: array_merge(): Argument #2 is not an array in /hsphere/local/home/c297646/website.org/core/model/modx/modx.class.php on line 2884 Fatal error: Class 'modContext_' not found in /hsphere/local/home/c297646/website.org/core/xpdo/xpdo.class.php on line 602
Reading from the error, I get that there's an issue with 'modContext_' in the xpdo class.

I just uploaded the latest build of Revo to overwrite any missing files and after starting the upgrade process, I get stuck passed the Installation Summary @ setup/index.php?action=install. When I submit the install form, I get a HTTP Error 500 (Internal Server Error). I'm not sure at this point what to do.

Any help will be appreciated

My environment:
PHP 5.2.14 and MySQL 5.1.51

Issue resolved. I emptied the core/cache directory and we're up and running.

2.0.8 fixes a critical cache error which can lead to pages displaying blank, just in case you didn't know.

Just wanted to post here that I just had the same issue with a site that I'd *just* put live!

After having a near heart attack, and finding this thread, clearing the cache directory definitely helped, AS WELL as realising that the hosting account was over quota, so I bumped the disk space up, which resolved the issue too :-)
