@chris No, I actually missed that point. I just made it and now it works as usual again Thank you very much guys

Your issue is solved, you don't need to use that plugin anymore, Tutrix mentioned that plugin as an option to solve the issue you had, which is solved now.

Then navigate to Dashboard > Forums > Dashboard admin page, click on the button.

Did you do this step after executing?

i've now installed the Better Search Replace.
The following URL is currently in the database under "Avatar":
//www.igl-home.de/wp-content/uploads/wpforo/avatars/lorenz_20.jpg

What do I have to enter in Better Search Replace and what should I replace it with?
when i replace "//www.igl-home.de/wp-content/uploads/wpforo/avatars/" with "/ wp-content /", nothing changed

I attached a picture of the database entry

best regards

try without these characters (`)

UPDATE wp_wpforo_profiles SET avatar = REPLACE(avatar, '/igl-testseite/wp-content/', '/wp-content/');

or use the plugin Better Search Replace

I executed the command, however, without a change. What else could I do?

best regards

Please execute these SQL commands in PhpMyAdmin > Your Website Database > SQL tab:

 The red wp_ is a prefix in your case it may be another word

UPDATE `***wp_***wpforo_profiles` SET `avatar` = REPLACE(`avatar`, '/igl-testseite/wp-content/', '/wp-content/');

Then navigate to Dashboard > Forums > Dashboard admin page, click on the button.

I had set up a test page with wp-staging and it was even called "IGL-Testseite" but why this was now transferred to the live page is a mystery to me. Is there any way to fix it? is there a tool with which I can change that?

thanks for help

best regards

Please delete your website cache and if you have cache plugin pls exclude wpForo from the cache plugin, also read the below topic about cache to get more info.

https://wpforo.com/community/faq/wpforo-and-cache-plugins/

And a question.

Was your WordPress root \igl-testseite\ folder, did you move your WordPress folder from there?

wp-content/uploads/wpforo/avatars/myavatar.jpg

Both above urls you posted seem wrong.

Have you moved or changed paths of your Wordpress site?
