    can i downgrade whmcs from 5.1.9 to 5.1.7 ?

    Hi,

    after i upgrade my whmcs from 5.1.7 to 5.1.9,

    one of my whmcs customized module can not work and show with whmcs error,

    but whmcs has no ideal about when to fix the error,

    so,i think if i can downgrade from 5.1.9 to original 5.1.7 ?


    thanx

    I think only way to downgrade is to restore previous backup.

    Yes unfortunately all will be gone.

    Edit: BTW why dont you upgrade to latest version? Seemed to be working fine so far, or your custom module works with older version only?

    Well i don't think that is possible to downgrade actual database to older version, as structure of Database changed after each new upgrade.

    Downgrading can lead to possible vulnerabilites in the script which can increase chances of being hacked/attacked etc.

    Therefore, not recommended.
