Error while changing avatar [MyBB 1.8.15]

[EHRA]

Hello everyone, I recently discovered an error message in my forum. It occurs only when a user changes the avatar. Image of the error message:



It is important to note that the avatar is successfully changed even with this error message. Anyway, I'd like to know if there's anything I can do to fix this error message.

Thanks for the support.

I've tried changing the PHP version to 7.0, but the problem persists. I noticed that the error message only appears when you need to resize the avatar image. If anyone knows how to solve this, please help.

This typically happens when you don't use the correct separator when defining the height and width of avatars. See here and review settings accordingly.

Thanks Wires, with your help I can correct the error. I did the following:

Home »Board Settings» Profile Options

View Forum Posts
It was like this: 100|100
Corrected for: 100x100

Maximum Avatar Dimensions
It was like this: 100|250
Corrected for: 100x250

That is, I changed the "|" by "x". That simple detail is who was causing that error message.
