Hi Olivier,
I have just upgraded my website to Joomla 4 and installed your Pro version 7.3.3, which I believe is the right one for J4.
I get an error message on the backend (I have other issues as well, but this only appears on LNE Pro):
Deprecated: substr(): Passing null to parameter #1 ($string) of type string is deprecated in /home/customer/www/cyprusholidaysguide.com/public_html/administrator/components/com_installer/src/Helper/InstallerHelper.php on line 267

Any idea what this is? And how can I fix it?
Thanks and regards from Cyprus,
Charis Theocharous

Hello Charis! I visited Cyprus (Limassol) briefly a few years ago, the coast was beautiful there.

What is your version of PHP? The error is in the Joomla installer, LNE probably triggered an area that was not used by other extensions. What is your version of Joomla 4? Some older versions are missing deprecated fixes.

Note that 'deprecated' messages are not errors or warnings, just indications that a future version of PHP will consider these issues as errors. So you should be good to go!

If the install is blocked because of the error (which can definitely happen as errors get in the way of the json calls), turn off error reporting and disable debug during install.
Olivier.
