Thank you viotto,
Edit topic button is available for Usergroups who have “Can edit topic” permission in granted forum access.
I suppose the users Usergroup is Admin and they have Full access in forum settings.
You should navigate to Dashboard > Forums > Settings > Forum Accesses admin page, edit the Full access, make sure the “Can edit topic” permission is enabled.

Hello,
thank you for your reply.
I already had all permissions enabled since I am Admin, but still same issue.

@viotto,
You’ve checked usergroup permissions, not forum access.
You should navigate to Dashboard > Forums > Settings > Forum Accesses admin page, edit the Full access, make sure the “Can edit topic” permission is enabled.

I add some info: my colleague logged in with his moderator account.
Buttons all display well from his Moderator account: https://imgur.com/a/8m8q6pw
But my Administrator account misses the Sticky, Edit, Delete, Unapprove buttons 🙁
Hi @viotto
1. Please edit the top category and the forum of topics you check and make sure Admin Usergroup is attached to Full Accesses forum accesses. Both, the top blue panel (category) and the forum of topics should have correct Usergroup-Forum Access configuration.
Then navigate to Dashboard > Forums > Dashboard admin page and click on the [Delete all caches] button.

2. Make sure you have Administrator or Editor user role in WordPress. The forum Usergroup is not enough. Forum checks WP Role and wpForo Usergroup and makes sure you have sufficient status in Website to be able edit other users topics/posts
3. Make sure the Edit, Delete timeout is not reached in Dashboard > Forums > Topics & Posts admin page. The Edit and Delete actions are limited by time.

Solution 1 worked: somehow the forum permission is set as “Standard Access” for Admin by default.
Setting it to “Full Access” solved my issue! 🙂
Thank you so much for your support!
