Important Notes

MainWP is not responsible for the files that you upload to your sites.

The File Uploader extension doesn't allow uploading the . htaccess file. This Extension upload files directly to your server, so treat it with the same care you would when uploading a file via FTP. Not all web hosts permit all file types to be uploaded. Also, they may not allow large file uploads. If you are having issues, please check with your host first. If you are having issues with uploading files, be sure to check that you are trying to upload a supported file type and that the file size is not over the limit declared by PHP Max Upload Filesize and PHP Post Max Size on your MainWP Dashboard server.
