Back end broken

Joomla version 3.10.8, VirtueMart version 3.8.8

I updated Joomla on 2 April and checked the front end and everything looked fine. My client adds and edits the VirtueMart products from the back end, I don't, so I didn't know there was a problem until she told me about it a few days ago. When trying to edit a product, add a new product (or anything else) when the button (Edit, New, etc.) is clicked it brings an unformatted page with menu links which I've attached a copy of. The Products link leads back to that page but the same things happens when Edit, New, etc. is clicked.

I don't know if this a bug but I didn't know where else to put this. I'm not sure that the problem happened when I updated to Joomla 3.10.8 because my client hadn't used VirtueMart in a couple of months, so it could have happened before that.

Any help with this would be greatly appreciated.

Looks like your JS has an error and is preventing the menus etc rendering correctly ... check the browser console for errors

I have many sites happily running or have run on this VM/J combination so there is no inherent problem with these

Thanks for the info. I checked the console and it says "This page is in Quirks Mode. Page layout may be impacted. For Standards Mode use "<!DOCTYPE html>"." I have no idea how to solve this or why it is happening now and hasn't happened before. Any ideas?

First, you have to study:
https://developer.mozilla.org/en-US/docs/Web/HTML/Quirks_Mode_and_Standards_Mode

Second, check your code for administration VM has right code in head (inspector code - CTRL A or CTRL I)

Result send there

1. I understand about DOCTYPE but I have no control over the DOCTYPE of the back end of VirtueMart so I don't know what I can do about that.

When I view the page source for the bad page that comes up when I click on a product no DOCTYPE shows - there is not even a head section. The first lines of the source are:


All of the other pages in the VM back end show the correct DOCTYPE.

2. When I check the administration code by using CTRL I, the only things of note there are:
   a. Render Mode: Standards compliance mode
   b. X-UA-Compatible: IE=edge

I will say that I am not using Edge and haven't tried using it but I doubt that is relevant.

Do you think if I reinstalled VirtueMart that it would correct the problem?

As GJC said this does look like a JavaScript issue. This page may help you understand the use of the Console for js issues.

A reinstall of VM may resolve this. Test on a copy of the live site, just install the full VM package over your existing installation.

I have discovered and fixed the problem. A few months ago I changed the PHP version to 8.0, reviewed the front end, and it was fine so I thought that everything was working. My client apparently has not been working on the back end since then and I didn't think to test it so when she tried to use it a several days ago and had the issue I didn't immediately think of it. At any rate, I have changed the PHP to 7.4 and the back-end is working again.

Vm is not compatible full with PHP8

We found the "last" problem. https://forum.virtuemart.net/index.php?topic=147821.0
and as he said, it worked in FE, he did not notice.
