Media Library / File Upload Issues on Multisite

I’ve got two sites on this multi-site – bulkingtoncongregational.org and arcchemel.org.uk. The Bulkington site seems to be working fine but the arcchemel.org.uk site is having issues with the media library and file uploads. It’s taking several minutes for the media library to load at times and if I try and upload files it gets stuck. Sometimes a refresh will show the file is there but not always.

Any ideas where I can start to troubleshoot this as it’s on the same multi-site set up as a site that’s working fine?

    Hi Jon

    I hope you’re well today!

    Since it’s a multisite installation, both these sites are using the same WP core and same server configuration so my bet here would be one of these three things (for the start):

    – either there’s some problem with domain configuration/DNS (though that’s rather unlikely)
    – or it’s related to some specific setting of the sub-site (e.g. some option set in theme or one of the plugins – only on that site)
    – or (most probable, in my opinion) there’s a theme/plugin conflict that affects that sub-site only

    I’d start with a standard conflict test then. The procedure means temporarily switching the site to default Twenty Twenty theme and then switching off all the plugins, clearing cache (if there is any on server) and checking if the issue is gone.

    If it’s not, it would mean that it’s not a conflict and further investigation would be necessary. But if the issue is gone, then start enabling plugins (and theme as first or last thing) back one-by-one, after each one testing the site for the issue and once it starts to happen again you’ll know that last enabled plugin (or theme for that matter) is the reason.

    Then we could look into it more to see why it’s causing the problem and how to, possibly, solve it.

    Best regards,
    Adam

    Thanks for this. The main user has just told me things are working again now and I hadn’t done anything so…?! I’ll have a look at some plugin stuff though it’s pretty consistent from one site to the next as they’re pretty much clones of one another. I’ll come back if I hit any issues.
