In lieu of hearing from any support here I talked with my host for a bit to see what we could find. Looks like they may have resolved by turning off pagespeed:

Can not edit pages with the theme enfold. At first I received a couple of
modsec errors

[Tue Sep 24 18:04:29 2013] [error] [client 10.30.5.49] ModSecurity: Rule

whitelisted the following.

<LocationMatch “/wp-admin/admin-ajax.php”>
SecRuleRemoveById 3000086
</LocationMatch>

We get the same thing.

Tried raising the PCRE limits.
/usr/local/lib/php.ini :

pcre.backtrack_limit = 10000000
pcre.recursion_limit = 10000000

/usr/local/apache/conf/modsec2/custom.conf

SecPcreMatchLimit 150000
SecPcreMatchLimitRecursion 150000

Did no good.

In the code we found that it was failing at

Customer is using wp 3.6.1
customer stated he has installed the latest version of enfold

no errors for the site specifically coming up in apache other then the modsec
errors.

But I believe we have resolved the issue. There was a issue the wherepagespeed_module was interfering with the loading of the edit page.

avia-modal.js,qver=0.3.1.pagespeed.jm.GwFNp0CbNe.js:77

We turned off pagespeed for now

If you want we can turn this on again and enter a entry in .htaccess like the following.

<IfModule pagespeed_module>
ModPagespeedDisallow http://myserver.com/wp-admin/*
</IfModule>

Would appreciate any follow up from the support here to see how we might get everything running with the pagespeed module since thats nice to have.

Thoughts?
