How to update to 2.1.5

If you are currently using version 2.1.4, you can perform the update using the Package Manager (Administration Center > Package Manager). There you should see a notification about 2.1.5, including a "update your forum" link. If you do not see this notification in the Package Manager, please run "Fetch Simple Machines files" from the Scheduled Tasks page (Administration Center > Maintenance > Scheduled Tasks), and then try again.

If you are currently using any version from 2.1.0 to 2.1.3, you can use the process described above to apply previous update patches successively until you reach version 2.1.5.

If you are currently using any older version of SMF (including SMF 1.x, SMF 2.0.x, or one of the SMF 2.1 Betas or RCs), you can upgrade directly to 2.1.5 from whichever version you are currently using by using the "Large Upgrade" package from the Download (https://download.simplemachines.org) page. Be aware that using this upgrade method will require you to reinstall any customizations that you have added to your forum, so if you are running SMF 2.1.0 or higher, it is recommended that you apply the successive patches instead of using the Large Upgrade.

If you are having problems downloading the patch from the admin panel, you can download the patch package from the Package Manager Updates (https://custom.simplemachines.org/upgrades/) page and install it via the Package Manager, as you would any other mod package.

Please refer to the Online Manual for more details about patching (https://wiki.simplemachines.org/smf/Patching) and upgrading (https://wiki.simplemachines.org/smf/Upgrading).


Finally, as always, please do not use this topic for support requests. You will receive a much quicker and better response by posting in the 2.1.x Support Board (https://www.simplemachines.org/community/index.php?board=254.0).

Thank you for using SMF!

Simple Machines

Congrats on the release, well done and a heartfelt thank you to all contributors! :)

Congrats on finishing the upgrade. It would have been fantastic if you would have implemented the use of other payment processors rather than only offering PayPal.

Love the addition of webp support!

Thank you. It's a cracking platform. Thanks for all your work on it.

I am seeing some errors since upgrade from 2.1.4 of: "Undefined variable $sid"

Here:  /forum/index.php?PHPSESSID=jdt7128kpso14k9l80oas1dhsf
/forum/Sources/QueryString.php (Line 677)


669: // Let's do something special for session ids!
670: if (isset($sid) && $sid != '')
671: $buffer = preg_replace_callback(
672: '~"' . preg_quote($scripturl, '~') . '\?(?:' . $sid . '(?:;|&|&))((?:board|topic)=[^#"]+?)(#[^"]*?)?"~',
673: function($m)
674: {
675: global $scripturl;
676:
[b]==>677: return '"' . $scripturl . "/" . strtr("$m[1]", '&;=', '//,') . ".html?" . $sid . (isset($m[2]) ? $m[2] : "") . '"';[/b]
678: },
679: $buffer
680: );
681: else

Just a transient error or is there something I need to do?

Congratulations on completing the upgrade! It would have been even better if additional payment processors were included instead of relying solely on PayPal
