[garikello]

Hi,

Just updated VM to latest 3.6.4. and now I have an error.

After trying to open any of the product pages I have error: Class 'vmLanguage' not found.

This is what debugger gives out:

I have Joomla! 3.9.12 Stable with multilanguage setup.

Any ideas?

Adding to your post, I got:

Error: 0
Class 'vmLanguage' not found

... With VM 3.6.4 after selecting any payment method and clicking confirm order, so rolled back to 3.6.2

Hello, i have exactly the same problem... Nobody have an idea ?
My shop is down, unable to show products.

Example : https://boutique.energie-sante.ch/materiel-therapeutique-aimants-chromotherapie

The issue is solved and will be addressed by Max himself shortly I guess.

Give him some time to put the fixed version up.

Seems it only happened in a few installations when VmConfig was loaded by a third party extension already.

[thefbi]

OK, but i cant wait.
So i have to apply a backup of my site, the problem is the latest backup i have is from 2 days (i dont have backuped just before upgrade => Error).
So i have 3 orders that i dont wanna loose.

Can you please tell me what are the tables i have to backup / restore to conserve this records (user, order, etc) ?
So i can restore my site and after that, restore the updated database.

[StefanSTS]

This is the router.php for /components/com_virtuemart/.

It is modified by Max and worked in my test. Use at your own risk, please.

[StefanSTS]

Given your over 100 posts here and doing an update in your live site without testing in a test environment first, I feel you have missed to read some important posts.

1. ALWAYS make a backup right before update.
2. ALWAYS test in a test environment.
3. ALWAYS make a backup right before update.
4. ALWAYS make a backup right after update.
5. Make another backup and test it locally.

PS. and make some backups when you feel like it.

[thefbi]

OK, it work, thank you.

Yes, abitually i make a backup, but it is only when you dont make it there is problem
And for the tests, yes, i have to do it, but with Akeebabackup pro, a restore is make in 3 minutes...

[StefanSTS]

If you have Akeeba backup Pro you might consider setting up a cron job for your daily full backups and two or three db backups per day.

Then you can sleep much better. ;-)


PS. If you want to thank someone, thank Max with a membership subscription if you don't already have. He was very quick about finding a solution.
And it wasn't obvious that there was an error as I explained earlier. This happens sometimes because the developers cannot test all scenarios for every shop. That is why a test environment is so important.

[thefbi]

Yes, i already do this. But in fact, the latest backup is from yesterday morning, and i have updated th VM yesterday evening. In the journey, they was 3 orders...
But if i had saved before, I wouldn't have had any problems...

I will thinking about subscription. And about a test environment too

[Mike J]

This may help someone.

After updating to: VM to 3.6.4 the confirm order button redirected users to an error page that produced the following error regardless of what payment method was selected:

0
Error: 0
Class 'vmLanguage' not found

I noticed this time after updating to VM to 3.6.4 again, a notice saying: a table was noninheritable and that a table was added. Same error so I went to Tools & Migration / DB Tools / Optimse Database function and used that function, now my error has been resolved.

Hope this helps someone.

Just subscribed right now Thanks at the team !

[StefanSTS]

Thanks to thefbi. ;-)

I am myself just an "external" so I don't get a pizza or anything for recommending to join the VM membership, but since this great piece of software is given for free, I like to remind everyone, if they make a fair amount of money with it, to share a small amount of that with the people that give the opportunity for everyone to make a shop with little or nothing.

Thanks again
Stefan

You're right, I have a lot of websites, only 2 shops with Virtuemart. Most of my sites are showcase sites or with other types of components.

I use professional components that are paid for year-round, and I have no problem paying for it. It's true that Virtuemart is free, and as a result, we don't really think about contributing. We don't think about it less when we don't have to pay to use an extension

And i am installing a hosting with test environment especially for my Virtuemart sites I prefer make it online.
