Hi,
Thank you for the reply. I’ve tested out your suggestion on a small test site we have that on which there’s no WP caching enabled, and cleared the browser cache as well.
Updating from 4.1.7 to 5.0.2 on the site results in the display corruption. Deactivating and deleting the v5.0.2 of the plugin (checked that the directory was removed!) and then installing v5.0.2 afresh didn’t resolve the display issue either.
