I have the following problem on the JA template: (Joomla 4.2.5, PHP 8.1)
When I use my own addthis-account there are no links showing up in ja template now. With the demo account of joomlart it worked. I tried several themes.
I have an account and code on the addthis.com. I paste inside template manager-> ja_template-> custom-code section – (before-body) but does not work!
I'm able to show AddThis code on joomla 3 with Ja Bookmark v2.6.3 plugin. Social sharing icons showing up.
I have been using this site for testing.
