Large Scale Import Issues

    So I have been trying to move a large media library (approx. 1100 files in approx. 120 folders) from Filebird to MLO. Something in the process seems to be causing a timeout when about half to two-thirds of the folders are imported – the files in the unimported folders seem to be successfully assigned a category (they do not show up as uncategorised) but the categories themselves do not show up anywhere in the UI at all. I’ve managed to import the same configuration to Catfolders with significantly less issues so I am assuming this issue is MLO specific.

    Hi there,

    Thank you for writing!

    Here’s what’s most likely happening: with ~1,100 files across ~120 folders, the import runs as a single long request. When the server cuts that request off partway (a PHP max_execution_time or web-server timeout), the per-file category assignments already written stick — which is why those files don’t show as uncategorised — but the final step that writes the folder tree/order MLO uses to draw the sidebar never completes, so the affected folders don’t render even though the terms technically exist.

    A couple of things that usually get this across the line:

    1. Raise the server limits before importing. If you can edit php.ini / wp-config.php (or ask your host), bumping max_execution_time (e.g. to 300) and memory_limit (e.g. 256M+) gives the import room to finish in one pass.
    2. Import in smaller chunks. Rather than all 120 folders at once, bringing them over a portion at a time sidesteps the single-request timeout entirely.

    Let us know if this helps.

    Kind regards!
