first, thanks for this great contribution, I guess that was a lot of work.
until now I was using an older version of htc now I installed just to manage the information pages from (information pages unlimited contribution) and stay up to date. I use the version HeaderTags_SEO_V_3.1.0-1. After installation i tried to add a pseudo page information.php?info_id=16 and it didnt work, the information.php was recognized by the script and the titles i set there were correctly shown. so i searched within this thread and found an other person who changed this line in header_tags_seo.php:
else if (($result = FileNotUsingHeaderTags($parts[0])) === 'FALSE')
to
else if (($result = FileNotUsingHeaderTags($parts[0])) === 'TRUE')
so i changed that line. after this change i was able to add the pseudo page, and set the title, also the title is stored in the database correctly. but not in the title tag I changed the sort orders and tried a lot of combinations, no chance. after i added a second pseudo information page and set the title there, it took the changes and showed the title tag i added, but the problem is, now the title of this information page is shown on all other information pages. the root information.php has no individual titles only the pseudo pages but all pseudo pages got the same title in output, not in the database, there the titles are differrent for each page, like it should be.
sorry for my bad english i hope you could understand what I mean. may someone got input for me, I use STSv4.5.8 and followed the instructions for this also I use Ultimate SEO URLs v2.6 and Information Pages Unlimited v2.04.7
