    Hello, I have a AWS EC2 server with a WP image. I also purchased the All-in-one Unlimited Extension.
    When I want to import my backup file, it says:

    Maximum upload file size: 2 MB.
    How-to: Increase maximum upload file size or Get unlimited

    Even with the Unlimited plugin activated, I cannot import my 200Mb website.

    Can you please help here? Or is there a contact email?

    Hello, I have exported correctly from the origin.
    the file obtained is 374MB
    I have installed the ALL IN ONE MIGRATION plugin
    Then I installed the ALL IN ONE MIGRATION FILE EXTENSION plugin
    The destination WP is a completely clean installation.
    When trying to import the file does not advance of 0.0% and finally says that it could not be exported.
    what is the problem?

    I’m having an import issue. I’m trying to bring a copy of my live site into staging site and while the import meter hits 100%, i then get an error message reading “Unable to import”

    My max upload is around 430 MB and my file being imported is 327. I recently updated the All in One WP MIgration plugin too, so that’s up to date.

    I have a screen cap of the error message. My staging site has almost no plugins active due to it being recently created.

    I love the All in One Migration plugin. I use it all the time. I have a client that is hosting via Network Solutions and they are awful. My site export is about 470M and I’ve increased my php limits to accept this file. It gets to about 3-4% and stalls. I contacted Net Sol about it and they simply want me to hire one of their professionals to migrate the site. I said no way because when they did that the last time they installed a bunch of garbage along with WordPress. Anyone else have issues with Network Solutions and found a workaround? I hate going old school but looks like I’ll have to ftp all my files, then database, then import settings. What a pain. Man, I hate Network Solutions.

    Hi the plugin works well on export, but hangs up on import, stalling at aprox 50%

    File size is 175 MB (the extension is installed)

    I have modified the php.ini file as follows
    -memory_limit is set to 256M
    -max_execution_time is set to 500
    -mysql.connect_timeout is set to 400

    I’m using WP 4.9.9 with PHP 7

    Any suggestions ?

    Thank you

    My exported file size is 400MB. I’m trying to import it into a GoDaddy WordPress site. I installed the plugin on a brand new installation but it restricts the max file size to only 100MB. I spoke with GoDaddy who instructed me on how to increase my max upload file size to 500MB by creating a .user.ini with the line “upload_max_filesize = 500M” – but your plugin still only accepts a max file size of 100MB. So I’m still stuck with the plugin refusing to accept my 400MB file because its too big. I confirmed the max upload file size on my site IS 500M so my ini file change has taken effect, it just for some reason doesn’t control the setting specific to this plugin. Is there some other way I can get at this 100M setting?

      Please read these this guide: How to Increase Maximum Upload File Size in WordPress

      The easiest way to figure out the problem is to request error logs from your hosting provider for your website, then examine them around the time when you tried to upload the file.
      You will see what limit you have encountered and increasing it will solve the issue.

      The settings in PHP that you likely need to adjust are:

      • `upload_max_filesize` – set this to a value > than your backup
      • `post_max_size` – set this to a value > than your backup
      • `memory_limit` – set this to a value > than your backup
      • `max_execution_time` – set this to 0 (infinite)
