    Thank you for this software — it seems to be working from what I can tell from the cache statistics. But perhaps you might have some insight into the following error being reported in our error_log:

    #7 /home/.../.../.../wp-content/object-cache.php on line 1296

    You found a bug. Thanks! And thanks for adding the SQLite version. It is indeed relevant.

    Darn it! — I thought I defeated that particular one. It’s something to do with SQLite 3.7, and how it handles unique keys in tables.

    I’m near to releasing a new version, so your report is timely.

    (Squeeeeeee …. the sound of the bug-zapper charging up … )

    Thank you Ollie. It’s good to know I’m helping. I’m looking now through the other error logs and I’m finding similar “unable to execute” errors (either ‘column is not unique‘ or ‘database is locked‘). Copying these below just in case they offer any additional clues.

    This one is from the root error log:

    This one is from the error log in wp_admin:
