I had wp smush installed (free version) but had not used it. I got wp smush pro and installed as per instructions. as soon as it was installed I got a blank white screen. I deleted the free version of wp smush (via ftp), and the site returned, to my great relief. I am now bulk smushing and so far it has spent about 15 minutes and the progress bar says it is still on the first image. Is that right? I do not want to do the "turning off and on all plugins" thing if at all possible it takes an age, inconveniences everyone including clients, and sometimes preferences etc are lost.The site does use a lot of (reputable) plugins, as most do these days, and up until now has worked fine. Please could you tell me if the white screen was to be expected, if the long time it is taking to smush sounds right, and if there is a list anywhere of plugins that it conflicts with. Thanks!
PS I should add my internet connection can be a bit flaky - would this have any effect?
