phpBB SEO Premod for phpBB3 support forum. This premodded version of phpBB3 includes the three different type of URL rewriting for phpBB3 by phpBB SEO. It comes with several other Search Engine Optimization mods installed.
The error seems to tell that you are not using the last version of the phpbb_seo_class.php file, or that you did not implement all the zero duplicate code change in it.
set_cond() is a method added by the zero duplicate mod in the phpbb_seo_class.php file.
I just wanted to update the Seo Mod from 0.6.2 to 0.6.4 and then comes this error message: Call to undefined method phpbb_seo::set_cond(), but unfortunately I can not download the Zero Dupe Mod to resolve the problem.
I have installed the No Dupe and the Zero Dupe and I only need the update of the Zero Dupe Mod. Why the download of Zero Dupe Mod is locked?
Oops Okay, I overlooked this small but fine detail. Thank you.
Meanwhile I have found out that the error message appears if I insert the topical phpbb_seo\includes\setup_phpbb_seo (During the update from Ultimate Seo Mod from 0.6.2 to 0.6.4). The topical file is much bigger like the previous file.
