Luckily I took a VM snapshot before I upgraded. :-) I'm rolling back for now.

I was using Chrome, but tried in Firefox and at the login screen after attempting to login was informed that "No ACL setup yet! Denying access to everyone."
However, in Chrome I can use the "Open link in new tab" trick to navigate to my ACL and see that it is still there and configured. I assume this is due to cached credentials.

Very annoying experience... What can i do?
I see on screen:
Warning: openssl_encrypt() [function.openssl-encrypt]: Using an empty Initialization Vector (iv) is potentially insecure and not recommended in /home/content/sys/html/dokuwiki/vendor/phpseclib/phpseclib/phpseclib/Crypt/Base.php on line 1017

People with black screen problems: check that your gallery plugin is uptodate.
@lima2018 your problem seems unrelated. please open a proper bug report.

Disabling the Gallery plugin resolved the black screen issue for me.
revnarwhal
andi, thanks for the suggestion.
I had already restored my VM from last nights backup. Updated the Gallery plugin, as well as other plugins, and am making a current backup of the VM, then will attempt the upgrade again and report back.

Updating the gallery plug-in before updating the wiki did the trick for me as well.
Someone might want to make this a more obvious warning in the release notes. I did see that it recommended updating the gallery plug-in, but made no mention of what we had been seeing. It would have been nice to know *why* the update was recommended.
revnarwhal
Updated the gallery plug-in, then used the Wiki Upgrade page to apply the update. All looks good at this point. Thanks for pointing this out to us, andi.

How can i update the gallery-plugin if the screen-links are not 'clickable' id the darkened screen?
zaffizaff
thx a lot,
it also worked for me. I just went back to the previous version (downloaded old version and just overwrote the current one) then went into the extension manager and updated the gallery, then updated the dokuwiki with the newest version.

you can also manually update the plugin by FTP

So i did, but that didn't solve the problem. I uploaded the 2016-12-22 version.
Then i blocked the plugin in the plugins.local.php file.
$plugins['gallery'] = 0;
Situation did not change.
andi
when doing manual updates and changes, always be sure to refresh the DokuWiki cache by touching the conf/local.php

Problem of the black screen solved after clearing cache directory on the server and the browser and 'touching' config files. 'Headers already sent' problem persists, but that is for another post.

I'll ask the same question someone else asked. How am I supposed to disable/update/anything the gallery plugin when I can't even login? Anything I do on my wiki just show the same stupid black screen..
Does installing the older version blow out the pages?
andi
Temporarily disable Javascript in your browser, then use the extension manager to update the extension.
Alternatively just delete the the lib/plugins/gallery folder and reinstall the plugin afterwards.

I did exactly this as well:
root@server:/var/www/html/dokuwiki/conf# nano plugins.local.php
<?php
/*
* Local plugin enable/disable settings
* Auto-generated through plugin/extension manager
*
* NOTE: Plugins will not be added to this file unless there is a need to override a default setting. Plugins are
* enabled by default.
*/
$plugins['authad'] = 0;
$plugins['authpdo'] = 0;
$plugins['authmysql'] = 0;
$plugins['authpgsql'] = 0;
$plugins['authldap'] = 0;
$plugins['gallery'] = 0;
Then I had refresh the browser cache (CNTRL + F5) on my windohs machine.
I am now able to access the Login and admin functions. :D

Updating the gallery plugin solved the black screen issue for me. However, the Admin and User buttons are no longer working and are just reloading the current page.
Any ideas?

Maybe it would be good to update all plugins prior to update Dokuwiki. This may be checked and noted when using Update-Plugin. Also the Update-Plugin could move the updated/changed files into another location to provide an rollback/restore to the previous version? This function should be callable through a special URL, so if Wiki is "black", one could trigger a rollback with it.
