Apologies for the inconvenience.

Could you please allow me to take a full backup of your site (files and database) so I can investigate the issue locally and identify the root cause?

Hi Matt.

Sorry, but "Username and password do not match or you do not have an account yet." Check details!

On all my sites, I can use PHP 8.2, 8.3, and 8.4 without "crazyness" , so it must be single case.

I think I know why.

1. This file „/templates/shaper_helixultimate/css/template.css” was locked by .htaccess file rule Header always set X-Content-Type-Options "nosniff" - please remove it and save changes.

2. Please also check if nobody deleted content of template.css file. If that file is empty, please reinstall template or upload file using FTP tool. Also check file permissions, it should be 644.

Then it should be OK.

Hi Paul I've comment out that line in the htaccess and verified that the template.css is still there and permissons are 644. I've also reset the password.

Thanks

looks that Joomla cannot load that file?!

Ok, I will check if I can login now.

It looks that there is something with your Joomla itself.

I only logged and went to Templates

I cannot help more until you will not fix that.

Hi, Im nolonger getting that error. Just deleted the cache and gave it some more disk space

Thanks, indeed helped with Joomla.

And about problem, you forgot to delete/comment that line in .htaccess file, or save changes - hahaha ;)

Menu looks Ok now, you own me soda

hahaha, i owe you more than a soda! Thanks, Now using your crystal ball, how could that have gotten changed in the middle of the day? I was driving at the time and no one else that has access would touch the htaccess file?

Anyway, solved. And You got to the destination safely.

Mark topic as solved, and you see next time, I hope not soon with "urgent", hahah

Have a wonderful day.

same issue, multiple sites.

Just had this occur on multiple site which I had not been touching at the time. Developer tool says MIME mismatch. Reloaded Helix Ultimate with no change.

Two-step temporary workaround:

1. copy {template}/css/template.css to {template}/css/template2.css
2. Edit {template}/index.php to use template2.css instead of template.css This is a workaround. Somewhere in 'the system' the file named template.css was being blocked, but not other files in the same directory and .htacess does not appear to be doing it.

@Phillip,

Every day I see lots of websites, I have many too, and everything works fine on all of them, so I can't figure out why, all of a sudden and for no apparent reason, Joomla has simply stopped ignoring the presence of the template.css file. This is normal css file. If you or your hosting provider updated the server configuration, the MIME types might have been overwritten. This is the only reason I can imagine.

You can also use those lines inside .htaccess file

# Forcing correct MIME for CSS and JS files
AddType text/css .css
AddType application/javascript .js

@Matt, please add it too, It's best to add it right at the beginning.

A stronger alternative

<Files "template.css">
    Header set Content-Type "text/css"
</Files>

As 'magically' as it appeared yesterday, the problem is resolved today.

Though they won't admit it, I expect my service provider got some security setting wrong, but that's just my opinion.

Thanks for your attention on this matter!

Thanks, indeed crazy behavior. hahah
