Is your forum within a forums folder?

The free, "Lite" version. I have it running without much hitch on two other of my sites.Now that's a interesting question because technically I suppose it is. The domain points to a folder in the file manager but the folder name isn't part of the URL. This might possibly cause a problem with rewrite rules, although for years i have successfully had the forced www rewrite rule in effect with no issues.

Thanks for all the help and suggestions/questions fellas. It's good to be on the receiving end of help from here every now and then!:D

Did your webhost reveal anything ?

I also had our forum in a forums folder and DBSEO would not work for us also, I ended up moving the forum into the root, and everything worked 100% after that.

I didn't check server logs yet but I will, thanks.It seems to work just fine, just the .htaccess rewrite rules kicking the ISE error. Is that what you were having?

Without the rules, the DBSEO works just fine except of course, all internal links generate 404s.

This may help youWhich of these settings do you have set to in the dbseo-cp

[forum_id]
[forum_title]
forum[forum_id]

I had to set all mine to forum_id before it worked

Hmm this was with or without the forum folder?

You put the forum on root, AND used forum ID number? I much prefer the titles than the numbers and have the settings for titles, throughout..

I should mention I am using vB 3.8.7

After I had moved out of the forums folder, before in the forums folder I could not get the add-on to work at all. Afterwards I had to set all the settings to forum_id to stop all the 404's

I'm using 4.2.2

I had a similar issue on some URLs on a 3.8.7, turned out it was the settings in the stopwords for DBSEO which were generating the 404s. Some of the definitions such as the words 'and' 'or' etc.

I have DBSEO installed and working exactly the way I want it to on two other 3.8.7 installations. Only on this latest one am I experiencing the issue with the .htaccess.
