HOANGVANHIEP When I installed the "Gemini Flarum" utility, the website immediately crashed, can anyone help me?
luceos HOANGVANHIEP try removing that extension with composer. See https://docs.flarum.org/troubleshoot for more information.
treyb HOANGVANHIEP I have found that after installing an extension, and this happens, wait 5 minutes and hard refresh. Your site should be working again.
