Since a week ago I suddenly get the following error on sr.midneid.at/qa
A Question2Answer database query failed when generating this page.
A full description of the failure is available in the web server's error log file.
Is there ANY possiblity to debug this without access to the apache server log as I am on a shared server without any but basic rights. I really hope there is a way to solve this problem without setting up everything step by step and copying questions out of the database over :(
I already tried to delete all plugins from the plugin folder, it did not change anything so I reverted this.
Edit:Based on pupi1985 and steven2's answers I got the queries, they exceed the 8.000 character length limit for a post so I pasted it to pastebin.
Edit2: With the updated help I get the following query as failing. Please note I replaced the real username with "user". The username was correct but I think it is not a good idea to share that information :)
