@JRA3, wow... wierd!  Perhaps you had a dodgy ftp of core elgg code somewhere along the line.  Try replacing the whole installation (leave you renamed Mod folder there and alter the engine > settings.php to match the original installation)  and if things seem normal again, have a go are swapping your mod for the standard mod... it may work.

I've tried everything above, but no solution.

vectus, what errors are you getting?  did you turn on display_errors in .htaccess?

Hi evan,

Thanks for your quike response. I get the following error:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 16 bytes) in /home/content/v/e/c/vectus2010/html/sl/engine/lib/database.php on line 271

also Entities on site shows item: object :izap_videos 1. however, i have remove izap_video from the mod.

Thanks! 

Try hitting yoursite.com/upgrade.php

I think you're probably having the memory issues as idiotter above. He did have a low memory problem on his shared server + php.ini max mem coded wrongly. look at your php info() - then we can tell. you should at least 128M avail ;)

No single page should require 64M of memory... increasing the memory isn't solving the problem (though it may alleviate the symptoms for a while).

@EW - just drawing the analogy ;-)

if you read back above - ID's prob *was avail ram - i logged into his account to zap all his plugins, fixed his php.ini and enable/disable issue went away.. worth looking into - ID had 96M assigned but still had probs until i forced ram to 128M.

i did the upgrade, but still getting the same error.  can i upgrade the memory my self..

I agree with Evan. A page on a clean install of Elgg should never require more than 64 MB. When I have helped people with this in the past it always ended up being a bad plugin or a bad ftp transfer. One approach is to just blow away all the code and the database and start over.
