I have installed the zero duplicate mod, with the advanced url rewrite mod already installed. When I went to my forum I got the following error message:

Fatal error: Call to undefined method phpbb_seo::set_cond() in /home/a5176469/public_html/index.php on line 38

I have installed this mod twice and both times this has hapened.
Can anyone tell me how to fix this?

I find it curious that some of those who frequent a site dedicated to search engine optimizations don't use search themselves. A cursory search with google turned up this:

Anyway, the set_cond method is added in phpbb_seo/phpbb_seo_class.php by the zero duplicate mod, make sure you have all the required code added there for the zero duplicate, should be enough to fix the issue.

PS: If it still doesn't work, try copying phpbb_seo_class.php from the premod; it contains all the optimizations offered by phpBB-seo.

Thanks for the info, I will copy from the premod.
I did do a google search, I even tried translating replies from the french forum, but I couldn't get it to work. Hopefully copying from the premod will solve the problem.

Implementing the zero dupe mod fully does it too
