Hello,
Articles Anywhere is a mandantory plugin in our system.
We using SP PageBuilder Pro and JDownloads extension.
On our site we give access to anybody to download some files, but unfortunately if choosing a category which have many files needs pagination. For example : j4teszt.srv11.joomlaportal.hu/index.php?...y&catid=6&Itemid=141 which is our DKÜ category. So, the JDownloads pagination is shown on the right upper of page, but if select one of those eg. 3 the the user redirected to 404 or our custom 404 error page.
If the Articles anywhere plugin is disabled the site seems to be works fine.
SP Pagebuilder Support team find that problem because firstly I guess maybe the SP Pagebuilder the source of mistakes.

Ca You help me?
Thank You!

Here you are!

it's only 42 byte, is it real?

Hello,
This seems to work. I will restore SEF and system cache and test for a while.
After testing, I will put it on the production site and report back to you.

Looks OK!
Previously, there was a similar problem with the display of the blog, but I did not attach importance to it, because it was typically not important (few news articles), but with downloads, since there are a large number of files at startup, it was unfortunately inevitable to involve the support of the relevant component makers.
The SEF and System cache are ON, the client browser cache had to be cleared.

The next step will be to reinstall Akeeba's Admin tool, because at first I thought there was a problem with it.
Thank you for your cooperation.
