eduardobarcello; automatic_search is set by the gItemStats vBulletin options, config.php and config_itemstats.php is not used at all.
The problem with adding 200 item's is that it has to open 200 thottbot/alla/etc pages one at a time at the time of posting (with auto search on) in order to retrieve the information about each item. This can be a lengthy process depending on how quickly your server can talk to the database site and how well it can process the resulting information.
Support for this addon is a little tricky as the code that actually does the retrieving of the item data is done by code not written by me and I am not quite prepared to support that, however I will attempt to, but it may not be in a timely manner. Basically what I am providing here is ease of installation of
Itemstats by eliminating the need for editing config files.
Reeve of shinral; I am not quite sure why that is happening for you. It would appear that you might have two [item] modifications which declare that function?
