I am using Flarum on localhost and installed SimpleMDE using composer. It installed successfully and then I activated the extension from admin section. A popup occurred saying "Please wait", after that I was in the admin section (til that point everything was good). Now as I clicked website title to go to the homepage, the layout was completely broke. Although, the admin section is still working fine if I access it using the URL.
Update: I can't even uninstall the extension. Whenever I click on uninstall it says "Oops! Something went wrong. Please reload the page and try again.".
