latest update v2.9.3 error

Hello!

After I updated to the latest version of Elementor (2.9.3), I have received the following error when editing to pages:

strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior

When I reverted back to v2.9.2 my pages open icons in Elementor were missing (although the functionality was still there)

What is the best way to get pass this error?
