This chapter on the manual page shows the actual Version is 1.35

but claims that all Versions starting with 1.36 will need to upgrade step by step.

Thanks for help

Check requirements

MediaWiki 1.35 requires:

• PHP 7.3.19+
• One of the following:
  • MySQL 5.5.8+ (or equivalent MariaDB)
  • PostgreSQL 9.2+
  • SQLite 3.8+

Since Version 1.36, MediaWiki only commits to supporting upgrades from two LTS releases ago (see phab:T259771). Upgrades from older versions of MediaWiki will have to be performed in multiple steps..

If you are using PostgreSQL, please also read Manual:Upgrading Postgres.

For more information, please read the Manual:Installation requirements and Compatibility.

Right. They're planning on introducing that change for 1.36.

I'll change "since" to "from" to make this less confusing.

@DKinzler (WMF) I've added an example upgrade scenario. Could you check to see that it is correct?

The warning ''change the name of the .htaccess file back" under web browser instructions to run the update script is confusing to me. As a user running the web upgrade script I don't know 1) what .htaccess this is talking about or 2) what I would name it back to. If someone has more of an understanding, it might be worth adding points 1 & 2 to the warning. Thanks :)

sidebar: Some of us don't permit use of .htaccess on our systems, making use of the sites-enabled/--.conf file mandatory for security purposes.

In older versions, namespaces were defined only in database (as far as i know... maybe i had bad implementation).

All pages under namespaces stopped working after upgrade - solution was add all namespaces from DB table to LocalSettings. Worth mentioning.

Namespaces have never been configured in database. Maybe you had an extension that was adding those, and then you didn't install it on upgrade?

Possibly a stupid question, but... latest stable version (right now) is 1.34 according to the sidebar. The answer to the frequently asked question "How do I upgrade from a really old version? In one step, or in several steps?" is "It depends: If you are upgrading from MediaWiki 1.4 or older, you should upgrade to MediaWiki 1.5 first." These are the current alpha and beta versions of mediawiki, right? Would it be better to give instructions that make sense for the current stable release? Is it ok to upgrade from 1.30.2 to 1.34, for instance.

These are the current alpha and beta versions of mediawiki, right?

No. MediaWiki 1.4.0 came out on 2005-03-20. It is very much not the alpha branch of MediaWiki, which is MediaWiki 1.35.

Thanks for the quick reply! Your answer is smart and my question was dumb, as I suspected it would be.

There are no dumb questions, worry not. :-)

The run the update script section makes several references to explicitly running PHP5, even though all supported versions of MediaWiki now require PHP 7. Could someone please update this?

{{sofixit}}

Upgrading from e.g. 1.10 to 1.27 on PHP5 is still supported.

I'm trying to update an installation of MW 1.34.1 and get the following error

PHP Parse error:  syntax error, unexpected '?' in .../w/maintenance/Maintenance.php on line 376

Which PHP version do you use?

PHP 7.3 FastCGI

The "??" operator was introduced in PHP 7.0. Looks like your server is not using PHP 7.3 but an older version, at least from the command line.

You should check if the php binary for 7.3 is installed somewhere else and you need to run scripts with the full path to that binary, like /usr/bin/php73 or similar

bump during install

Where did you download VisualEditor?

the upgrade process for MediaWiki should be as simple as WordPress IMO awesome project. serenity and limitless peace. Michael Ten (talk) 07:48, 27 March 2020 (UTC)

I'm seeing a discrepancy between what my Ubuntu server reports as the current installed version of PHP (7.4.1) and what my MediaWiki Special:Version page says is the current installed version of PHP (7.0.33).

The instructions say that the versions of PHP used at the command line and by MediaWiki can be different, but I'm not sure how to resolve it (and the instructions just say to "ask your hoster"). Any suggestions, or could someone point me to instructions? Thanks! Huwmanbeing (talk) 10:57, 21 December 2019 (UTC)

It's likely that you have multiple PHP versions installed on your server. Do you use an software bundle, such as XAMPP?

The software management mechanism in these software bundle is not the same as the software management mechanism of the operating system. The operating system does not automatically recognize software bundle. So when you install PHP using yum or apt, it will still install, even if the package bundle already has PHP.

Sorry I am new to this. Should this command apply to all folders and files within the images folder or just to the folders? I checked the permissions on my site and all the files under images are 644. Thanks in advance.

Only to folders. Folders need to have the executable bit to be accessed. However, files shouldn't have the executable bit (otherwise could lead to a security risk)
