I'm trying to upgrade PHP from 5.6 to 7.3 in a jommla website running with Joomla 3.9.11
But I get the following errors:
Using $this when not in object context

I have put on the error reporting in the joomla website.
What I see then on the screen is:

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; plgSystemJCEMediabox has a
deprecated constructor in /home/stadskanaporta/domains/stadskanaalportaal.nl/public_html/3test/plugins/system/jcemediabox/jcemediabox.php on line 32

followed by:

Do you have any idea how to solve this problem?

I've recently bought and installed JCE Pro 2.7.15

Thanks in advance for your support.

Kind regards,

Please uninstall the version of JCE MediaBox you have, and install the latest version - https://www.joomlacontenteditor.net/downloads/mediabox

I don't think this is a JCE issue at all, but rather related to another extension you have installed which is not PHP 7.3 compatible. From the call stack you posted, the culprit may be mod_flexheader3. If you disable this module, do you still get the error?

Just because you're not paranoid doesn't mean everybody isn't out to get you.

I did unistall JCE Mediabox and installed JCE Mediabox 2.0.11
Same problem.
Then I tested with mod_flexheader3 disabled and the problem was gone.
So it seems that the Joomla extension Flexheader3 causes the problem with PHP 7.3.

I now know how to solve the problem.

Thanks a lot for your support.
