all variable products in my shop are so slow. I don’t know why, but if I click others simple product the website is ok, but the variable products no.
When I go see your site it loads pretty fast for me. Having said that you might want to look at improvements like noted here:
If you create a variable product without this extension right now, do you get the same problem?
thanks for your answer.
I deactivated a lot of not really necessary plugins and now I solved the problem.
So, was some conflict between plugins.
Here the list of plugins deactivated:
Add-On User Registration di Gravity Forms
Advanced Code Editor
Artbees Themes Captcha
Email Address Encoder
Envato WordPress Toolkit
Export User Data
Gravity Forms Polls Add-On
Import users from CSV with meta
Media from FTP
WooCommerce Product Feed
Thanks for the update! It’s hard to know from the list which one might be the problem, but if you do need any of them you could try enabling them back one at a time to see which one was causing the issue.
