Hi @Suhaib_Al-Fahdawi,

You may wish to see this post here: An unexpected error occurred. You may have been logged out. Please reload the page and try again - #16 by Sridhar_Gutam

As noted in this post where that error message is discussed, it would be helpful to report on any errors from your PHP error log.

Also, could you please include your OJS version number (e.g. 3.2.1) in your posts - knowing this helps with troubleshooting.

Best regards,

Hi @Suhaib_Al-Fahdawi,

Great. Thank you. I’ll see if I can have a team member look at this and get back to you when they are able to.

Hi @Suhaib_Al-Fahdawi,

It looks like you’ve installed a version of the PKP Preservation Network plugin that’s not compatible with your version of OJS. Make sure to use the Plugin Gallery to install plugins – it ensures compatibility.
