message i am getting 

This page isn’t working

domain is currently unable to handle this request.

HTTP ERROR 500
  • ok all 

    the old version we was using some groups still are at the moment, but they was using php 5

    but i didnt notice the hosting had php versions from 4 to 9

     

    i done a upgrade   , with adding a subdomain path for the update, and selecting that subdomain to use php 7.4. and the others on 5.

     

    i tried to removing the old version but the new version is still seeing the old data or using the old version but with its new coding, so when i say renamed the old version path, the photos on the new version didnt show , as soon i resumed the old name on the old version the images came back. i have edited the database config, to include the new version, but there still a few configs i need to do 

     

    and yes i have been making backups..

    its working right now

     

    but extending my thanks to those that have helpped or just gave me advise , thanks everyone
