CLASS 'JTOOLBARHELPER' NOT FOUND - 0-Error: 0 - on Joomla 3.8.13

[giofranz]

Hi guys, this morning I set up a new e-commerce on J3.8.13. Everything was fine but then suddenly I got the following error CLASS 'JTOOLBARHELPER' NOT FOUND on every VM Category Layout menu. I have changed some settings in configurations but nothing in particular come to my mind.
Is not the first time i use VM but is the first time I get this error. Products in home work fine, if click on those i get redirect in an auto generated path. Only menus don't work. They were working until an hour ago. Now nothing.
Any idea? TY in advance!
This is the website url http://demo5.webdojo.it ; this one of the products menu that used to work http://demo5.webdojo.it/prodotti/prodotti-alimentari-canapa

Actually all menus come back. Did nothing. Maybe some connection/cache/ obscure problem? No idea

Hi,

this is from GJC. That helped.

file administrator\components\com_virtuemart\helpers\vmdefines.php ~ line 162
uncomment
//JLoader::register('JToolBarHelper', JPATH_ADMINISTRATOR.'/includes/toolbar.php');

Maybe he is around later to explain it further.

Problem should be only in front end editing.?

Regards
Stefan

Hi Stephan, thanks for the help
the problem seems to be solved. As i said, it was matter of time. I cannot say why. Maybe problem on my server.
I will keep in mind your suggestion though, in case the problem shows up again!

Thank you!
