Hello,
after many tests on 2 websites, I am sure that the problem is caused by cache.
When a page is already cached by a different browser, the off-canvas login/register has problem. When a page is cached for the first time on the same browser, then it works.
If I disable cache completely, the off-canvas login/register has no problem and it works. It does not conflict with any other plugin.
Litespeed cache plugin uses ESI for the Woocommerce cart, so it works correct. I think, that if we make the off-canvas to use ESI cache, then it will work with no problems either for login/register, or for wishlist (icon and off-canvas).
How can we make the theme’s off-canvas compatible with this Litespeed ESI function?
Thanks
