Fatal PHP error

I tried to use the update tab to see if any plugins needed updating and got this message:

 Fatal error: Uncaught Error: Call to undefined function WPDM\admin\menus\remote_get()
in /wp-content/plugins/download-manager/admin/menus/class.Settings.php on line 307

Any ideas?

7.4

I am still getting the error when I visit the plugin update page (https://mysite/wp-admin/edit.php?post_type=wpdmpro&page=settings&tab=plugin-update.

Hi! Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email. In this case, WordPress caught an error with one of your plugins, Download Manager. First, visit your website and check for any visible issues. Next, visit the page where the error was caught (https://mysite/wp-admin/edit.php?post_type=wpdmpro&page=settings&tab=plugin-update) and check for any visible issues. Please contact your host for assistance with investigating this issue further. When seeking help with this issue, you may be asked for some of the following information: WordPress version 5.5.1 Current theme: CharityFoundation Child (version 1.8) Current plugin: Download Manager (version 3.1.08) PHP version 7.4.9 Error Details ============= An error of type E_ERROR was caused in line 307 of the file /public_html/wp-content/plugins/download-manager/admin/menus/class.Settings.php.

Line 307 of plugins/download-manager/admin/menus/class.Settings.php reads

$purchased_items = remote_get('https://www.wpdownloadmanager.com/?wpdmppaction=getpurchaseditems&wpdm_access_token=' . wpdm_access_token());

If you change this to

$purchased_items = wpdm_remote_get('https://www.wpdownloadmanager.com/?wpdmppaction=getpurchaseditems&wpdm_access_token=' . wpdm_access_token());

It works.
