hi @Justoverclock , just to let you know that I encounter an issue when using this extension. Feel free to check it when you got time.
[04-Aug-2021 00:55:09 UTC] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 8388608 bytes) in /Applications/MAMP/htdocs/flarum/storage/less/lessphp_rvpzy43ar9wss80s8gw08w0oo408co0.lesscache on line 3
I know nothing about .lesscache, 😅 however, after I increase memory limit to 256MB, I turned off the slideshow extension, and decrease memory back to 128MB, then no more php error. Just raise this issue, in case this will be helpful to you.
