Dear Support,

I am trying to upgrade my b2evolution version from [5.0.5-stable] to any newer version because it is getting old. But when I log in as Admin the Auto upgrade does not function. and I have the following error (see also attached screen capture). The website is (

Can you manually upgrade as instructed on your screen-shot?
Do you have a copy of the database before you attempted the upgrade?.
given the version of php, which is just on the edge, what version is the database engine MySQL ~ Maria etc?

In the middle of your screenshot it says "Your current b2evolution version is too old for reliable auto upgrade" ----> use manual upgrade.

For a manual upgrade you will want to transfer the files via ftp.
How did you install the current version 5.0.5

Download a recent version of b2evo, it doesn't have to be 7.1.5
6.11.7 would be fine and you'd be more familiar with the back-end management

  1. Ensure you have a backup of your database.
  2. Do not delete the /media directory where your images are, all text is in the database.
  3. Ask your host if they will upgrade your php. If you have cpanel you may be able to do this yourself, though php 5.6 should work.
  1. Make sure you have acopy of the database password which is in the [/conf/_basic_config.php] or make a copy of the file.
  1. Delete all files except as in 2 and 4 above.
  2. Using Filezilla or some other option upload the files from the download once you have unzipped them and have all the core directories available.
  1. Go to your site /install/index.php and follow the instructions

Hopefully all will work out. I am a bit concerned that you ask how to manually upgrade.

Please read especially from sections 5.1 ~ 5.2 ~ 5.4 You already have a database so 5.3 should not be required.
