Critical error "Uncaught Error: Call to undefined function trailingslashit()" after updating plugin to 4.5.15 about ilab-media-tools

Did it say what file or line? trailingslashit is a wordpress function so it should always be available, unless you are trying to run this code outside of wordpress somehow.

Yeah 4.5.15 doesn't even use trailingslashit in any of its changes (see 0326322).

4.5.14 changes do have the use of trailingslashit in one place in the changeset but its in a class that has already been using that function for six years now.

My guess is that something is either messed up with your wordpress install, or if you updated the plugin from wordpress.org or freemius, maybe the plugin didn't install 100%. I'd delete the plugin and reinstall it again.

I'm going to close this for now, but if you can get me a file and line number to see where the error is, I'll take a look at it.

@relaxdd did you get it sorted?

@jawngee yes, most likely the problem was that the plugin was not updated correctly
