ERROR MIME type ('text / html') is not executable, and strict MIME type

carlostegs

Hello!

I have Template from Gavick News, use Joomla 3.9.12, with PHP 7.3 and with component k2.

I wonder if anyone has a solution for this

I noticed that I have the following error on my website pages:
"MIME type ('text / html') is not executable, and strict MIME type"

After researching, I found that this is due to Joomla security recommendations from version 3.9.3 onwards to include the following line in .htaccess:
<IfModule mod_headers.c>
Header set X-Content-Type-Options nosniff
</IfModule>

I decided to turn to you to see if anyone has solved this type of problem to eliminate this error MIME type ('text / html') is not executable

Does anyone have a solution for this?

I look forward to a possible help

Thank you
Success

Hello
Thanks pankaj

Yes, the same problem occurs
After countless searches as I said before, I found that in reality the Joomla security recommendation, which put this code "Header set X-Content-Type-Options nosniff" next in the htaccess that causes this.

It is because of this that it causes this MIME error on websites.

If I remove the htaccess code the problem goes away, but I am concerned about its security.

What I would like to know is if anyone has any alternative for this without leaving the site without security?

wait

Hi
Latest version of Joomla is 3.9.14 that has all fixes, in this case you may write on the Joomla forum as this issue is not related with the template and about the code you want to use.
Personally i am not using any kind of code for this purpose on my sites.

Hello!

Thanks for your answer.

But on the Joomla 3.9.14 version, I have other Gavick sites and with Joomla 3.9.14 and everyone has the same MIME error (txt / html). This has nothing to do with Jommla version 3.9.12

This is actually a problem caused by the security recommendation by Joomla.

My intention is to find out if anyone would have already discovered a way to stay with the recommended "nosniff" security and solve the problem in another way.

Anyway, I appreciate your attention

I wish much success
A hug

This is why i suggested you to post on Joomla forum as this issue is not related to template and about the code you are using, as you said its same with default Joomla template as well.
