Can't upgrade/install plugins and themes

  • This is an issue I’ve been having since version 3.6.

    Currently when I go to update-core.php, I get the following error:

    You have the latest version of WordPress.
    Fatal error: Cannot access parent:: when current class scope has no parent in /…/wp-admin/includes/class-wp-upgrader-skins.php on line 602

    If I then try and install/update a plugin through that page (after uploading a “clean” version of the file) I’ll get the following error:

    Fatal error: Call to undefined method Plugin_Upgrader::init() in /…/wp-admin/includes/class-wp-upgrader.php on line 441

    I have tried not just deactivating, but deleting all the plugins I have installed. Currently only have Akismet installed and I still get these errors.

    Tried deactivating and using a different theme, that doesn’t work either.

    Uploading plugins and themes via FTP and then activating them via their respective pages, rather than going through update-core.php or installing via WP control panel, works.

    Contacted my host and they tried a few things to do with the server, turning off eAccelerator and the likes, but they came back to me saying it has to be a plugin.

    I thought I could just live with having to upload class-wp-upgrader.php file every time I needed to update/install, but since 3.7.1 I can’t even do that.

    Don’t know what else to do now!

    Interestingly, just installed JetPack, see if I could. After a few re-uploads of the above files, managed it. But on the Sharing settings page, in available services, I have the following error:

    Fatal error: Cannot access parent:: when current class scope has no parent in /…/wp-content/plugins/jetpack/modules/sharedaddy/sharing-sources.php on line 191

    Could all of this be linked?
