My site is under "maintenance mode" plugin while I encountered this error
The problem occurs when I click two links in a milliseconds interval then my page suddenly become plain white, then when I hit refresh. I got that error already. the second click that I've done is clicking the "Activate" of my theme.
I can access my webmail, cPanel, and FTP. I also tried renaming the folder of "maintenance-mode" folder under plugins, but still the same.
Anyone knows how to fix this? Thanks!
