@mstess – Sorry to read you have run into a WSOD issue … if the Reset Option worked earlier in the day then it most likely did not cause this directly but you may still need to start with NextGEN Gallery first.
You will need to use an FTP client (or your sever’s file manager). Start by renaming the /nextgen-gallery/ folder under /wp-content/plugins/ to something else (I recommend adding a ~ character to the beginning of the folder name).
Now try accessing your WordPress site and log into the Dashboard, and visit the Plugins > Installed page (this should give a message saying NextGEN Gallery is deactivated … don’t worry if it doesn’t … this step is important). Now, go back with your FTP client and rename the NextGEN Gallery folder back to its default (for example, remove the ~).
Now, there could be a plugin conflict going on here or at least it should be ruled out. Have you tried deactivating all of your plugins, clearing your browser cache (and site caches if you are using a caching plugin), then reactivating the NextGEN plugin? If the WSOD happens again, repeat the above.
If this fixes the problem then it was likely one of the deactivated plugins that was causing an issue. Now, retrace your steps activating each plugin and re-checking to see if the problem returns. If it does then that last activated plugin was probably the one. Keep reactivating and in most cases it is also best to keep checking after each plugin, sometimes there may be more than one plugin on a site that will create an issue. If you do find one (or more) plugins causing this problem we would greatly appreciate your feedback on them so the developers may address them as soon as they can.
Also to note, in rare cases it may be the theme itself that is causing a conflict so while you have just the NextGEN plugin activated you might consider temporarily switching to one of the default WordPress Twenty series themes and see if this corrects the issue as well.
If the problem still persists after all of this we would still want to know, even more so, as we will still want to sort out the issue and may need additional details.
Thanks!
– Cais.
