Hear is what I know.
Using Dreamhost for my site
Piwigo is the ‘One Click Install’ app
My site, rabidpixels.org, has been down for a few weeks
DHost techs worked on it from their side, they say its a problem with the PHP out of date and the PEAR is up to date.
When I go to the app management window on the DHOST website, I have the latest version.
I have done a few updates with the app since 2013, the last update rendered my Pwigo useless and I have not been able to get it back online nor has the tech service at Dreamhost.
Please let me know what to look for, or I can give admin rights to someone to have a look at it from the back end…its not a big site nor hold any real value other than for family and friends.
