Updating PHP in Parallels Plesk 12
When I first tried to install Backdrop on my Virtual Private Server I found there to be a problem with the version of PHP that came provided with my VPS, and I set about installing a more recent release of PHP5.5. This seemed to be working well, but in recent days I have been puzzling over why I could not get Backdrop to scale images when uploading them, either to create thumbnails or to scale an image to a size specified in image field properties. [This is called 'image resolution' which I find somewhat misleading - hopefully Backdrop could change this Drupal terminology.]
