Hi
On the contrary it creates me problems and I do not find any help for SEO as I used to get from SH404
Absolutely. 4SEF is in no way a successor to sh404SEF. It does only and strictly one single thing: SEF URLs. It does not have any SEO feature at all.
The simple SEO features that where in sh404SEF have been integrated into 4SEO (not all, some have been dropped as they were outdated), and if you do serious work today, 4SEO should have you covered in all areas.
4SEF is an absolute requirement if you were using sh404SEF in the past on a site, because it's the only way to maintain the same URLs as you had with sh404SEF. You must not change the URLs of a site, that's the only thing you can never do in SEO.
I have looked again at the one and only ticket you opened and I can see that you did not reply to my reply, so I assumed you figured it out.
What I don't understand in that ticket is that you seem to be using sh404SEF previously, but you asked me how to configure 4SEF to create URLs that are NOT the same as sh404SEF. That's strange and I'd really like you continue discussing in this ticket so that I understand what's happening.
As for trying 4SEO, we do not have any "trial" version as this is strictly forbidden by the GPL license of Joomla. We can only give you the full version but cannot have a limited version.
As with 4SEF and all our extensions, we do refund when someone is not satisfied with what our extensions do for their use case.
