I tried to migrate the files from db to filesystem, under admin/stats -> Button "Blobs to Disk".
Result: undefined
error_log:
PHP Warning: mysqli::query(): (00000/0): in /qa-include/qa-db.php on line 197
PHP Question2Answer MySQL query error 0: - Query: SELECT blobid, content, format FROM qa_blobs WHERE blobid>=0 AND content IS NOT NULL
Could this be due to the size?

PS: My hoster has set up the CPU timeout to 260 s, so this should not be the problem. I also get the undefined very quickly after hitting the button.
