Well, if you look at the mentioned line you'll find `??` and as far as I remember that is an issue in MediaWiki that relates to the used syntax. For details, see [0, 1] where it has been noted "... A user reported in #mediawiki today with this exact situation (using php 7.1 but his webhoster had php cli symlinked to to php56)." @kghbln Given that users are hitting this issue, I think it is time to see to it that this is backported soonish and have a MW 1.33.1 release.

I have created a back-port of one of the commits. Let's see what happens. Anyways I am pretty sure that we will not see a new MW release soon. This is just the way it is.

Thank you for your help, I've applied corrections suggested, the script update.php lokks ok... but now I have Parse error: syntax error, unexpected '?' in /home/.../maintenance/Maintenance.php on line 882.
the line of code in the script is : $this->setParam( $options, $bits[0], $bits[1] ?? 1 );

@henrigilabert I believe your hoster has to remove PHP 5.6 from the system. The change will only give you a graceful failure the issue will persist no matter what you do.

[henrigilabert]

According to mediawiki info the PHP version is 7.1.30 Cordialement, - Best regards - Mit freundlichen Grüßen - Met vriedelijke groeten - Saludos - Salut - Hälsningar - Ciao Tél. 06.75.23.84.11 email henri.gilabert@sla.lu<mailto:henri.gilabert@sla.lu> Henri GILABERT

I am not sure if you read the linked information.

[henrigilabert]

I did and I double checked the PHP version of the hoster, see below [cid:image001.jpg@01D53BE8.FCF788F0] Cordialement, - Best regards - Mit freundlichen Grüßen - Met vriedelijke groeten - Saludos - Salut - Hälsningar - Ciao Tél. 06.75.23.84.11 email henri.gilabert@sla.lu<mailto:henri.gilabert@sla.lu> Henri GILABERT

I created a help page for this

update.php lokks ok... but now I have Parse error: syntax error, unexpected '?' in /home/.../maintenance/Maintenance.php on line 882. the line of code in the script is : $this->setParam( $options, $bits[0], $bits[1] ?? 1 );

Again, this is a syntax related issue because MW 1.33 requires "... requires PHP 7.0.13 or later." [0] but somehow your PHP linked library uses anything but PHP 7 even though `Special:Version` shows 7.1*. Whether you have SMW installed or not, this issue will remain as long as your hosting provider is linking to an unsupported PHP. Details about the `??` (Null coalescing operator) can be found at [1].

There is nothing I can do ?

What about contacting your hoster about this? I have already suggested this.

[henrigilabert]

I got an answer from the hoster : the command line has to pb php71 to have it running php 7.1 Now the issue is fixed but I have an other problem from update.php telling me that my composer.lock is not up to date Cordialement, - Best regards - Mit freundlichen Grüßen - Met vriedelijke groeten - Saludos - Salut - Hälsningar - Ciao Tél. 06.75.23.84.11 email henri.gilabert@sla.lu<mailto:henri.gilabert@sla.lu> Henri GILABERT
