Hey @magicfilou,
Thank you for reaching out! Before anything else, if you have a caching plugin or caching system (provided by your hosting company), please delete/flush the cache.
The new version has had quite a few changes for the JS and CSS files, so if your website is pulling the cached old version of the files, things will break.
If you’ve already done this, or if this solution does not work, please contact us via our website’s contact form (here: https://slicewp.com/contact/#gf_3).
In the contact form, please add screenshots with the issues you’ve encountered so that I have a visual of the issue. Considering that these screenshots could contain private information that you may not want to share publicly, you may want to contact us via our website. This is a public forum, so any information that you share here is public.
As soon as you contact us via our website, I’ll get back to you as soon as possible.
Thank you and best wishes,
Mihai
