No i did not have any mod Added during this. As other people playing with forge confirmed they did not have that issue, I fixed the problem with a complete re-installation. deleted .Minecraft folder, uninstall and reinstall of Minecraft, made a Java update and installed latest version of Forge (forge-1.15.2-31.1.37). Thanks for your help !

i'm sure of that . the issues appears when Forge is loaded, desappears when forge is not loaded. i ve been playing on that server for 4 years, and i never had this issue before. Also : i have that issue on solo maps too when forge is loaded

As you recommanded in downloaded the latest version (31.1.35) but i'm sorry to say that i still have the item frame issue.

So i'd rather install 31.1.27 ?

Minecraft 1.15.2 and the latest version of Forge (forge-1.15.2-31.1.0-installer.jar)

As the tittle says : i can't break any items frames when forge is loaded, not with the hand or with any Tools, though other players can break my items frames. I'm quite sure this issue is related to Forge since i can still break items frames without Forge. The issue is the same on a server or on a local offline game.
