Do you need to add autogeneration back?
If your site has many pages that add everything is very difficult.
I think that autogeneration is necessary. And something that is not needed can be disabled manually
There are 2 different things.
in version 1.3 - autogenerated means that canonical urls is displayed only in source code (generated from urls), no database record is created.
in version 1.4 generate button is generating record in database.
No problem to return 1.3 functionality back, I just need to rename it - autodisplay?
I removed this because canonical urls are not sef-urls. You (webmaster) should revise them and manually change them to other url if they have low quality value or they have similar content.
In version 2 is planned connection with gsitemap plugin. Only ulrs with record could be used.
So I can return Autodisplaying canonical tag but autogenerating records is not good.
It is necessary to try. When will be the release of 1.4?
I needed to update to 2.1.9 at first. Now you can download it. Its the same version what this site is used. No problem to return those preferencies back and add autodisplay back (for forum plugin)
I just found that if you want to use e_admin.php, your admin has to be in English.
No idea why, it's from original code.
I didn't notice this because here is English, but I use it on other site with Czech language and I was worried why it didn't work.
