Updater always hanging at stage 5 "Verify integrity - Parsing response failed."

This error I also got weeks before with another version on all-inkl.com webspace/host. As long as updates don’t work, I will not start using the solution productively.
On the Overview the only error in color (that I also cannot fix) is this one:

  • The PHP memory limit is below the recommended value of 512MB.

Any ideas ?

How is your Internet connection while downloading the update ?

Seems like the update.zip file is not downloaded correctly.

try downloading it manualy

then try a manual upgrade

Set your memory value in php.ini to atleast 512MB

memory_limit = 512M
