At first it used the same keywords for every page as it was grabbing the text from an article in a module and stopping there (a bug?). My q&d fix was to edit metagenerator.php to strip the first 50 chars of $thecontent so it skips over the troublesome text (line 126: $thecontent = substr($thecontent, 49);). I know there's a better way to do it but this method took less time than writing this review.
It seems you are not using last version. First, Metagenerator dosen't use sbstr() anymore, it uses joomla JString::substr for utf-8 support. Also what you are doing stripping the text is an option in last version.
Thank you very much for your review!!
Awesome Plugin, exactly what I needed!
The limit is system-dependent and is affected by PHP configuration. Future versions will exhibit a more user-friendly behavior should a memory limit problem arise.
