Help! I started deleting the telegramshare app. The site gives an error:

Fatal error: Declaration of IPS\telegramshare\_Application::get__icon() must be compatible with IPS\Application::get__icon(): string in /home/u68796/public_html/forum/applications/telegramshare/Application.php on line 25

I can't go anywhere, what can I do to fix it?

You would need to contact the author of that application for support, as this looks to be coming from a 3rd party application named telegramshare

I've solved everything, deleted it Application.php

Glad to hear you have the issue resolved
