VirtueMart 3.2.14
Joomla 3.8.7
Configuration:
Virtuemart/Configuration/Template:
Frontend default items per list view: 6
For 3 items per row: 6,12,18
Frontend Problems:
6 products are displayed.
If 12 products are selected - everything is ok. URL: ..../results,1-12
If we go back to 6 products, it again shows 12 products. No "results" in URL.
We choose 6 products again - now everything is OK. URL: ..../results,1-6
If in the configuration we choose Frontend default items per list live value that does not exist in For 3 items per row (for example 9.), there is no problem. But then, after the first choice, we can no longer return to 9.
Virtuemart demo:
Frontend default items per list view: 24
For items per row: 15,30,60,150 (default value because it is not set in the configuration)
At first we see 24 products per page, but if we choose another value, we can no longer return to 24.
If we do not use SEO, there is no problem.
