Issue: Fatal error

There is also a compatibility problem with the vb4 mod Easy Forms, when vaultwiki is enabled I get the following error when submitting a form

Fatal error: Allowed memory size of 12582912 bytes exhausted (tried to allocate 77824 bytes) in /home/bluedragon/public_html/forum/includes/adminfunctions.php on line 1365

when vaultwiki was disabled I was able to submit forms with no problem.

This is not related to any "incompatibility" with VaultWiki per se. As someone who has been using vb4 for several months now, I noticed that default vB needs between 16 - 24 MB memory on pages that require medium to large amounts of processing. If your limit is lower than this, it will be difficult to use any mods smoothly, let alone large modifications like VaultWiki.

Any way to fix it? what settings should my host set? etc etc.

Otherwise this wiki is of no use to me in its current state.

I would try a memory limit of 32M to be safe. On our site, plugins aren't loaded to memory and each page uses roughly 20 on non-wiki pages.

After some negotiation with my hosts support people they finally agreed to raise the memory limit on my hosting package to 20megs. This appears to have fixed the problem and I can now edit pages again in vb4. I tried getting them to raise it to 32megs but they said for the hosting package that I currently use this is way too much (and for what I pay for it, I have to agree with them, haha)

Thanks for the info on getting this fixed.
