Hello, I’ve looked into upgrading my account but I didn’t see any information about the upload_max_filesize.
Will the upload_max_filesize change when I upgrade my account or will it stay at 10mb? / will I be able to edit it?
Free hosting accounts are not upgraded in place. You just ordered a hosting account from another company (iFastNet, not InfinityFree). They can migrate your website to their premium servers if you ask them for it.
You can edit upload_max_filesize and post_max_size on most premium hosting platforms.
