I have been using phpbb for my forum needs for the last couple months. But I have had many problems with bots and other things. I had someone reinstall the forum for me a week ago because the bot problem was getting so outrageous and instead of just deleting every one, one by one, I started over. Now I am getting this error message (I changed nothing, so I dont know how this is happening) SQL ERROR [ mysql4 ] Incorrect file format 'dwt_sessions'  An sql error occurred while fetching this page. Please contact an administrator if this problem persists. I have been trying to fix the problem for the last 2 days with no success. Any suggestions on how to fix this? Someone told me phpbb is old and outdated and that I should get a better forum.. Advice? EDIT::: Fixed the problem, forum is working again. Still though - wondering if I should be upgrading to a better forum to prevent problems in the future? Possibly BurningBoard or Xenforo ? Anyone have experience with these boards?
