Invisible 500 internal server error?

Hello,

I have a few modx sites running perfectly (0.9.6 and 0.9.6.1), but today i installed two fresh 0.9.6.1.p2 for projects i’m working on, and apache returns an internal server error 500 for both installations. This is invisible (the page shows properly and everything seem OK) but if i try for example to validate with W3C tool i get this error blocking validation.

They are on 2 different servers, so is it possible this is related to p2 version?

Thanks

500 Internal Server Error

Nothing interesting in apache logs...

Anything’s possible, but there’s been no reports as such and it’s unlikely the patches in the current release would cause such behavior. We’d need MUCH more info before even hazarding a guess as to what’s going on. See my signature for more details.

Here are some Google results with some ideas:

Thanks for your replies.
I continue my investigation.
It’s most likely related to my server conf (i worked a lot on it last week), but in this case, i don’t understand why my "old" modx sites are working...

That could be cached pages. Clear the cache and see if one stops working.

I tried clearing the cache but 0.9.6.1.p1 still works with no error
To be absolutely sure, i made new installs, p1 and p2, on the same server.
The first is ok, the second give the 500 error...

500 Internal Server Error

Since nobody else reported similar, there’s something in my apache and/or php config that goes wrong with p2 version.
Does someone have an idea of where i should have a look at first?

I run Gentoo, php 5-2-5 as cgi (suphp), apache 2, mysql Ver 14.12 Distrib 5.0.44 (Gentoo OVH Release 2.09 for those who know OVH).

Maybe chmod issues related to suPHP? o_O

This is the first thing i thinked to but permissions seem to be OK...

Are you using the sample site to test this? If so, remove snippets one at a time until it stops. I’m betting it has something to do with recent AjaxSearch changes.
