Product Category reappear after deleting from product.

[magicstar]

Hello,

I have a strange issue that I would like your help.

On administrator mode, I access a product. I select to add a product category from dropdown list. Then I press save. The product category tab is empty. When I press F5 to refresh it appears.

Anyone knows how to solve this issue?

Thank you in advance!

If you have cache problem, this can be because .htaccess too, if you cache json type, else check your javascript console(F12 on PC) if you see some errors.
Deactivate all debug(set in Joomla config PHP debug "none") can help too

Find a developper that work for you, such problem is not so easy to find without checking files and debug, if you had not yourself the issue.
