[05-Aug-2021 11:36:43 Europe/Samara] PHP Fatal error: Cannot declare class dokuwiki\Menu\Item\AbstractItem, because the name is already in use in /usr/local/www/dokuwiki/lib/tpl/bootstrap3/compat/inc/Menu/Item/AbstractItem.php on line 20

Hi, please check in doku.php the variable $updateVersion.

The compat library are loaded for DokuWiki version older than Grebo.

$updateVersion = "51.3";

I can confirm I am having the exact same problem.

I can also confirm

$updateVersion = "51.3";

PHP 7.2.24, otherwise identical

I did some initial digging on this just to see if I could see anything obvious.
I don't know the dokuwiki codebase or the internal workings at all, but I added two debug strings to ./lib/tpl/bootstrap3/compat/inc/functions.php

global $updateVersion;
$dokuwiki_version = floatval($updateVersion);

error_log("Debug: dokuwiki_version == $dokuwiki_version updateVersion == $updateVersion");

define('DOKU_VERSION', $dokuwiki_version);
define('DOKU_VERSION_HOGFATHER',          51); // 2020-07-29
define('DOKU_VERSION_GREEBO',             50); // 2018-04-22 (PHP >= 5.6)
define('DOKU_VERSION_FRUSTERICK_MANNERS', 49); // 2017-02-19 (PHP >= 5.4 ???)
define('DOKU_VERSION_ELENOR_OF_TSORT',    48); // 2016-06-26
define('DOKU_VERSION_DETRITUS',           47); // 2015-08-10 (PHP >= 5.3.3)


// Load compatibility Menu classes for pre-Greebo releases
if (DOKU_VERSION < DOKU_VERSION_GREEBO) {

    error_log("Debug compat if: dokuwiki_version == $dokuwiki_version updateVersion == $updateVersion");

This results in the following log messages when going to edit a page, and subsquently clicking on the "Add image or other files" button

So something is causing the variable to not be set seemingly only when trying to call media manager from the edit dialogue via the button.

Accessing the media manager by other means yields no errors.

Same error here, did some manage to fix it?

[neo7904]

In my case, when I installed "Stale plugin", the corresponding error occurred. I solved the problem by deleting it. please use file content search to find php files that use the "AbstractMenu" class and find the cause. :-)

[Le1b1]

I solved the problem by deleting it.

Fixed it for me, too. Thanks!
