wbntff can you give more details about the "random" stops?
I just checked the source code of the extension for any issue but the extension essentially boils down to two lines of PHP code and I don't see anything that could have been broken by any recent Flarum update.
However this could be an extension priority issue. If any other extension influences the like permission it might overshadow this one. But even then Flarum is supposed to handle policy conflicts pretty well.
