# Error Message thrown

 * Hi – I’m troubleshooting what seems to be plugin conflicts. I had to restore 
   my site from a backup and Mailpoet3 is now throwing this error (repeatedly) when
   activated:
 * Notice: unserialize(): Error at offset 509 of 3039 bytes in /home/mtzobeqeky0p/
   public_html/codycalendar.com/wp-content/plugins/mailpoet/lib/Doctrine/Types/SerializedArrayType.
   php on line 27
    ** Should I uninstall and reinstall Mailpoet3? I think *this*
   particular error on my site happened when I restored it from a backup (it’s been
   one of those cascading issues not unlike remodeling a house – tear open one wall
   to find an issue and look! there are three sitting there needing attention).
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-message-thrown%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi there [@janet-white](https://wordpress.org/support/users/janet-white/),
 * Thanks for reaching out!
 * You can most definitely try re-installing your MailPoet plugins. Your MailPoet
   data should be left intact since it’s stored in your database, but since you 
   were having issues in the past, I’d recommend creating a full backup of your 
   site before proceeding.
 * Cheers!

 * Thanks for the response – tried that and it’s still throwing the same error message.
   Maybe I’ll need to delete the files in the database and start again. Might that
   work?
 * I’m not a coder, so not sure what the error is. And, I don’t really have time
   to do a lot of troubleshooting. I do have a mailchimp account I could switch 
   to, but I truly love Mailpoet for so many reasons. Especially with this website
   project.
 * Any suggestions would be most welcome.

 * If you delete the files in the database and you do a fresh install then most 
   probably you’re going to lose old data (subscribers, lists, newsletters, etc.).
   I wouldn’t do a full reinstall unless you’re okay with wiping out all the information
   and you want to start from scratch.
 * In this case, what you can try is manually uninstalling the plugin and then reinstalling
   it back via FTP. Here’s a guide you can follow:

 * Please give it a try and let us know how it goes!

 * Hi there [@janet-white](https://wordpress.org/support/users/janet-white/),
 * We haven’t heard back from you in a while, so I’m going to mark this as resolved–
   if you have any further questions, you can start a new thread.
