I am getting this error: Fatal error: Call to undefined method phpbb_seo::set_cond() in /home/****/public_html/phpbb3/index.php on line 37

And even if I upload original from a file I get the same error.
I'm still testing this before using it on my main forum.
Test forum 3.0.1

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 have latest phpbb_seo_class.php file but I'll check the zero duplicates code to make sure it is the source of my problem.

Just grab the file from any mod rewrite package and overwrite yours, should be enough

Hello,

I have the same problem.

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?

Please help me, dear Admin.

Bye.

Do you mean this download? You have to register to download it.

As HTTP 301 are to be used with caution, the downloads are only available for registered users.

From phpBB SEO Zero Duplicate V 0.6.4.

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.

Is it necessary to replace the file or not?

Greetings.
