All php settings are correct and files upload fine under Apache, but after switching to LiteSpeed the upload either times out or get error message "Could not move the file into storage, possibly a permissions issue", though I think that is just to do with cache in browser caused by the previous upload attempt not completing. Clearing cache in browser seems to solves that issue. But after clearing cache in browser the upload just times out again due to LiteSpeed not allowing the upload to complete. Now I have checked many different threads at this forum where several members (including LiteSpeed staff) suggest changing certain settings, which I have done, but none seem to work, if anything, randomly changing settings here and there just makes things worse, and now I have a LiteSpeed installation that has had so many different settings changed that may not have even needed to be changed in the first place. Suggestion: include an option in LiteSpeed that allows all settings to be reset back to default so a re installation is not needed (saves a lot of time). Anyway, can someone please specify the exact settings-only that need to be changed in LiteSpeed in order for a 512MB file to be uploaded successfully. It never used to be an issue in the past, but I guess some things have been added/changed in LiteSpeed recently which can cause small-medium file uploads to fail (512MB is not too big).
