It happened yesterday and now I just fell victim to it again, wordpress randomly refuses to display <?php the_content(); ?> within loops for pages. And every time its late at night, *sigh*. Anyone got any ideas?
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the Twenty Eleven theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
