I have item stats in my DF 9.2, but when I try to put an item, and make a preview of the post... the system freezes like 10 minutes, and no one can access the website in a while... what do you think it's happening?

Could be that itemstats is hanging on the data retrieval, and thus freezing the page

I would check your server error log

do you refer to the cpg_error.log ?, if is it, is clean do not have data in, and CHMOD is 622

Inside your hosts control panel, there should be a link to logs or error logs or something similar

my host doesnt provides that info, in the control panel

I receive an error log via email whenever there is a problem on my website. I, too, am experiencing the same problem. It appears that when the item between the or [icon][/icon] is type incorrectly, or if itemstats cannot locate the item in the query, it freezes the database. I receive an error in my email that says this"

On /Forums/viewtopic/t=63.html
While executing query "SELECT g.group_id, g.group_name, g.group_single_user FROM cms_bbgroups AS g INNER JOIN cms_bbuser_group AS ug ON (ug.group_id=g.group_id AND ug.user_id=54 AND ug.user_pending=0)"

the following error occured: MySQL server has gone away

I've experienced this error before in other situations - and it always has to do with query issues or loops of some sort. It happened in the first version of wowroster's armory sync for me.

I just tested this again, and sure enough, when I typed in the correct text OR if the item I typed in IS on allakazam's website, it works fine. When it is not, it locks.

Is there something in the code that is supposed to cancel the query after a few seconds if nothing is found?

I dunno, I just patch up Itemstats to work in DF
I don't know the detailed inner-workings of it

Well you're doing a good job on the porting - I'm going to check into this some more and see if I can find out what the problem is/if there's a fix for it.
