Hi,

Using the new BS3 template, we get the following message (also see attachment) every few days and no website displays.

0 - variable @grid-columns is undefined


A restore of the site, brings everything back in place - but what is the reason for this problem?
Any hints on where we can look for the reason?

Site is http://www.odsherredcamping.dk and is built on J3.2.1 and T3V3 BS3 Blank template.

Any help appreciated!

Cheers :)

Just updated to new ver. 2.0.2 framework released today, and hope to see the issue gone.

Can't find any specific mentioning of the problem in changelog though - https://github.com/t3framework/t3/blob/master/CHANGELOG.md
But maybe my issue is covered by other fixes...

Will report if I see the problem again.

Hi Henrik Holm Nielsen,

Please check again if you have modified any less file.
You should check careful for those changes.

Also, you can turn error reporting of Joomla to see more information about the issue.

Regards

Hi,

Only changes I'm aware of having made, is the ones i have in my themes variables-custom.less file.
I have included them here, but can't see if there is anything wrong in here?

@font-size-base: 13px;
@font-family-base-custom: Roboto;
@brand-primary: #428aca;
@body-bg: #ffffff;
@text-color: @gray-dark;
@headings-color: inherit;
@link-color: @brand-primary;
@border-radius-base: 4px;
@border-radius-large: 6px;
@border-radius-small: 3px;
@t3-module-bg: transparent;
@t3-module-color: inherit;
@t3-module-title-bg: @t3-module-bg;
@t3-module-title-color: @t3-module-color;
@t3-spotlight-background: @body-bg;
@t3-spotlight-text-color: @text-color;
@t3-footer-background: @navbar-default-bg;
@t3-footer-text-color: @gray;
@t3-footer-module-background: @t3-footer-background;
@t3-footer-module-text-color: @t3-footer-text-color;
@t3-footer-module-title-color: @text-color;
@container-lg: 1170px;
@container-md: 970px;
@container-sm: 750px;
@font-family-base: Roboto;


The fact is, that I have just experienced the same problem again and had to restore a backup to get up and running again.

This time, everything on the site was working when I made a minor change to a existing custom HTML module, and saved it - and then the site crashed!
Can't figure out why this would trigger any changes to any less files.

Have to admit, that I went into panic-mode and went for the restore asap for the customer not to find out it happened. Therefore I did not try to enable error reporting in Joomla to find any other information. But - I have a copy of the site on a testserver, and will try to reproduce the problem later today.

If anybody have any idea or suggestions, I'm all ears :)

Cheers

Hi Henrik Holm Nielsen,

Does your site return any error message?

The LESS compile require 128MB memory on your server. Please check if your server can meet the requirement.
For best, I would recommend to develop your site on your local computer (which you can set the memory_limit easily).
Then you can upload the result to your server.

Regards

Hi,

Sorry about the late answer - I never receive notifications from here, when new reply's have been made :(

I do have the PHP memory_limit set to 128M, and have several other sites working perfectly on the same server, using both LESS and T3V3. Allthough this is my first BS3 install.
And actually, I also develop the site on a different server (not local though, as I use 2-3 different machines on different physical locations). But I did earlier take a copy of the site and deployed on my development server, where the same happened. Not sure if this means I have the same issue on both servers though ;)

Cheers

Hi Henrik Holm Nielsen,

Most of hosting server will limit the memory_limit to 64MB.
You can check the memory_limit with Joomla at: /administrator/index.php?option=com_admin&view=sysinfo (PHP Information tab)

Also, if you still have problem, please pm your admin/ftp to me. I will check if there is any other issue.

Regards
