!! white page, can't login backend

Hi,
Please ask your server support to update your php version. Download Manager ( > 2.8.3) requires php version > 5.3

If it is not possible to update php right now. You can get back to old version. Download it from here https://downloads.www.ads-software.com/plugin/download-manager.2.8.3.zip

Sorry for the trouble.

Thanks.

Thanks! If I overwrite download manager to the old version, will it erase all my downloads etc or am I fine?

I just overrode with the old version and I still can’t get into the backend and also this is appearing at the top of my website Warning: include(wpdm-core.php) [function.include]: failed to open stream: No such file or directory in /home/content/92/8935692/html/wp-content/plugins/download-manager/download-manager.php on line 108

After that I updated php to 5.4 AND newest download manager and same issue.

new error

Warning: include(/home/content/92/8935692/html/wp-content/plugins/download-manager/wpdm-core.php): failed to open stream: No such file or directory in /home/content/92/8935692/html/wp-content/plugins/download-manager/download-manager.php on line 40

Deactivate and delete current installed version, then install old version using WordPress plugin installer.

Ok, thanks. I managed to revert to my old backup so now what is the proper prcocess to update Download Manager and the newest wordpress version (i am using 2.8.93 download manager)

Updating WordPress shouldn’t create any issue as you have updated your PHP version. This issue was related to WPDM and php version. Latest version WPDM works fine with WordPress 4.5
