Up until yesterday everything worked fine, but today the site of the articles are not loaded, and this message appeared 500 internal server error.
This request takes too long to process, it is timed out by the server. Should not be if it timed out, please contact administrator of this web site To Increase 'Connection Timeout'.
I looked at the error log: http://nuovecanzoni.com/error_log
and I realized that the problem could be the plugin "Related Posts Thumbnail".
I disabled the plugin and now all seems ok.
We can look in the error log and share your opinion?
