I have tried to upgrade from 1.5 to 1.6 several times, each without success.
I've tried through Softaculous and I've tried through 1-click-upgrade.
Via Softaculous it stalls at 95% installed, leaving the site messed up or inaccessible.
Via 1-click-upgrade everything seems to be installing fine until it is almost done and then this error message appears in the progress window:
[Ajax / Server Error for action upgradeFiles] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " Internal Server ErrorThe server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at
[email protected] to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
I have increased the hosting but the problem persists.
My hosting provider is not responsible for Prestashop's failure to function so they do not know what the problem is and will not look for it anyway.
In what way could the server be configured incorrectly?
Has anyone ever, in the history of the world, been able to upgrade Prestashop without a hitch?
At the moment my only option seems to be to start afresh and delete the 1.5 version because upgrading does not work.
Any ideas?
