Problèmes avec les filtres et la pagination

The way used previously to retrieve filters, was based on using session variables.

This was changed to allow viewing the category without filtering if a category menu item is re-clicked

But maybe we were wrong to change this as it creates compatibility problem with old custom templates, plus it the filtering variables are specific to category-id so they cause no problem when viewing different categories.

NOTE: that the new version (with the updated templates) will work with full page caching (Joomla system cache plugin) ...

in your opinion the configuration is joomla2.5 latest FLEXIcontent version?

mmm, i do not understand your question

I said, what is the best configuration? joomla 2.5 and the latest version of FLEXIcontent?

FLEXIcontent for both J1.5 & J2.5 versions is almost same, in J2.5 version:
- the new v1.5.6 author manager is missing, although not so important in most sites,
- also the basic CSV import needs to be finished and enabled
- the permission system in J2.5 is as good as FLEXIaccess
- there is some performance issue in J2.5 if you have many custom templates, since currently the XML parsing function cannot be cached [update: this was fixed]
- multilanguage configuration is a little more difficult/different in J2.5, but FLEXIcontent offers switching items and categories on the fly

Thank you very much ggppdk for this explanation.
