I have been getting these intermittent errors since an older version of XF and I was prior considering rolling back to an earlier Beta version of XF that did not give me these errors (beta 3 I think) but I am now on 1.1 and the errors are starting to get to me to the point that I am unable to ignore them any longer. I have gone over the following threads http://xenforo.com/community/thread...ared-statement-needs-to-be-re-prepared.24497/ and http://xenforo.com/community/threads/error-on-install.17901/ so hopefully brogan will not be upset and point me to them as they were not really helpful to me. I am not sure if allowing guests to post contributes to the errors but I did start allowing this when I upgraded to an older XF version and found that I had to wait for an update because of known issues with guest content, It was only after the update that fixed this issue that I started getting errors. (With so many XF updates for the life of me I cant remember what version I was running without the errors but was prior to Oct 20, 2011) The XF test scrip gives the OK "Your server meets all of XenForo's PHP requirements." and I dont have any logged errors to share so any suggestions on what I should suggest to my host to fix these errors would be appreciated.
