hellotocco on "[Plugin: EP Hashimage] Fatal error after update from 4.0.1 to 5.0.0"

Hey guys, the plugin was working great until this last update. Now I get this:

"Fatal error: Cannot unset string offsets in /home/rahran5/public_html/wp-content/plugins/ep-hashimage/system/core.php on line 48"

Any ideas?
