What does this mean please & thank you ;)

I submitted my topic under farming and I got this message, even though my topic was accepted I got this message and do not know what this means?

Joomla\CMS\Cache\Storage\FileStorage::_deleteFolder Failed deleting 881323c313238702f88aea8d8c6d79a3-cache-mod_menu-a7ffa6151018e40daf5c6c298d66dfd2.php

Can someone please tell me what this means please & TY

It might have been when I was doing some maintenance on the site. If your post appeared okay then should be nothing to worry about!

Good To Know! Thank You, Buzzy!
