I only found this out afterwards because the pre-upgrade warning doesn't tell you WHICH file it thinks is missing or corrupt, just that it thinks x no. might not be right; and after doing a full upgrade package upload - twice - I was confident it was a misreport. (I finally found out which file after getting back into the ACP and doing a file health check!! )
So, my questions are:
- Will the upgrade be incomplete due to this file being zero bytes at the time of running it?
- Is there a way to re-run the upgrade?
