Although the file is distributed with Joomla there is nothing in the core that uses it. It is probably being used by your template. It absolutely should not be enabled by default. You would only want to be using it when you have changed your template - and then only once.

You are right @brianteeman

Thanks @brianteeman for point me into the right direction.

Thanks @810 for give me the solution.

I'm closing this issue now

I have just update to 3.9.18 and get the following (PHP 7.4.3):

Hi please open a new issue with that warnings so we can take a look into them.

Just looked them up on 3.9.18 @MrTobyDog seems you are not running a real 3.9.18 please reinstall the core files from com_joomlaupdate and try again and check the content to up-to-date with 3.9.18 stable.

Thank you - I had reached the same conclusion! I originally downloaded the
3.9.18 update files from the link on the update screen on my website and
they identified as such, but after I got this error I checked re-installed
that update and noticed it was 3.9.11 although the name was 3.9.18! I
downloaded the file again from the Joomla site and it was OK - so it seems
as though the link on the update screen MAY have been wrong?

That sounds interesting. Please send me a mail with the details to tobias.zulauf[at]community.joomla.org so i can take a look and make sure this is not a general problem. Thanks.

Not sure if there was a solution to this but I was able to search around and fix the issue by going to each line and replacing every

if ($query != '' && $query{0} != '#')
TO
if ($query != '' && $query[0] != '#')

Basically, replace the {} to [] on all the error lines

Yes I did that. But fixed in latest release
