Do you using earlier 5.00 version while it’s not capable with update and it’s 2 years ago.
After 5.00 of image hover ultimate its stored and can’t delete until you manually delete. As plugins deactivate or update also can’t delete data.
If you facing error as using 5.00 later version kindly install and install latest version. Better you can try https://www.image-hover.oxilab.org/wp-content/uploads/2020/02/image-hover-effects-ultimate.zip beta version which will release tomorrow.
In 9.3.0 I added more than 600+ effects with 8 categories and 3 extension as you can integrate post, carousel or filter or sorting. Also I fixed some bugs like popup form rearrange issue.
If you using 5.00 earlier version kindly contact via Oxilab.org so I can share zip file while that’s was completely difference version.
