All the current releases of Sphider had a minor bug when doing an image search by url. The corrected code is available on the downloads page. The main Sphider 2.0 is designated by an “a” suffix. All of the PDO versions have a “c” suffix.
The ONLY file changed is search.php. And in search.php, there is only one line altered. A passed parameter “type” was having uppercase characters stripped. A column in the database image table “images” is “imgUrl”. The uppercase “U” was stripped and the query failed when it couldn’t find the column “imgrl”!
If you don’t use the “Image Search” your version will work fine. If you DO use the “Image Search”, the ONLY file you need to replace is search.php. There is no need to do a reinstall.
The embarrassing part of it all is that this problem WAS caught and corrected during testing prior to the 2.0 release. HOWEVER, that corrected piece of code wasn’t placed into the zip files, which shipped with the uncorrected version of search.php. 😳
