error 500 on /results,1-150 page

[Leila]

Hi all!
Category pages with product limit =150 ( url ends with /results,1-150) show error 500. Joomla SEF off doesn't help. When I change template to default the problem remains. .htaccess is joomla's default.
Hosting tech support doesnt see anything which can cause the error in their logs.
Virtuemart 3.4.2
Joomla 3.9.8
Thank you in advance

did u take any of the advice in this topic?  http://forum.virtuemart.net/index.php?topic=117042.0

unless you identify the 500 error no one can help you

The problem solved! I followed this advice "A WSOD can also be caused by a lack of PHP resources. Joomla + VM2/3 requires at least 128Mb of PHP memory, and preferably 256Mb." and increased php memory limit to 256m.
Thank you for help!

I would be really worried by such incompetent server support!!!  They couldn't find a basic 500 error like this??

You should at least name and shame as a service to others
