The last good version on my blog (PHP 5.2.17, memory limit 256M, WP 3.5, last weaver II theme 1.2.7) was FSCF 18.104.22.168. After updating any later versions - see title :-(
Disable all plugins - done, but no solution.
Non other updates (WP, theme, plugins) and version 22.214.171.124 stil running fine, but installing/activate 3.1.7.X the site crashing (no error message).
What can I do now?
