Some Admin Pages are Blank or 404’d

    I’m trying to export various sites from a multi-site network, in order to migrate to a new site host. None of the sites’ /wp-admin/export.php seems to work — in most cases, clicking “Download Export File” ends up with a blank page, rather than a downloaded file (the URL schema is: /wp-admin/export.php?download=true&content=all&cat=0&post_author=0&post_start_date=0&post_end_date=0&post_status=0&page_author=0&page_start_date=0&page_end_date=0&page_status=0&attachment_start_date=0&attachment_end_date=0&submit=Download+Export+File ) ; in some cases, it returns a 404 error. (I’ve tried every site on the network). I’ve disabled most of the plugins and still can’t find the reason.

    The WordPress install is up to date and standard. I’m pulling my hair out and would really rather not do a MySQL dump to the new host.

    TBH, I’ve frequently had trouble with the export code on even simple sites. Exporting a network just makes it less likely to work properly IMO. OTOH, I’ve rarely had trouble with SQL dumps. The few times I had trouble, some minor editing of the SQL dump file solved the problem.

    In either case, it’s important to first clean out all the unimportant cruft in the DB. These are often very sizable amounts of data and are frequently the cause of trouble. A clean, lean, efficient DB will give you much less trouble.
