The paths are all good. It seems every attempt to upload CreatePptx.php to the server fails as follows.
It gets uploaded and instantly gets deleted.
Not by me or anything I'm doing—I've got 25+ years LAMP stack experience and I've never seen this outside of some hosting security system.
Runs fine on DEV, entire app runs file and all the other files in PHPPPTX are there. Only CreatePptx.php is getting deleted on upload.
Any thoughts?
