 * Hi, I am having some issue with trying to upgrade from PHP 4 to PHP 5.
 * Some of my posts, not all of them, just some of them are becoming invisible. 
   The headings are still there, but all of the data is not appearing.
 * I had tried to work on this with my webhost, and there was quite a bit of investigative
   work done trying to see what was going on. But it was not solved.
 * I am interested in any suggestions or possible solutions.
 * I am using only a couple of plugins: blog reordering and a little ecommerce plugin.
 * the theme is arthemia.
 * Thank you for any assistance.

 * Have you tried:
 * – 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 default theme to rule out any theme-related problems?
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause
   problems.

 * Hi, I have tried deactivating all plugins. now things are really broken though.
   Whereas before, the invisible pages came back when switching between PHP 4 and
   5, now they are not. I am trying to figure out some work around because it isn’t
   all the posts, just some of them. I’m not sure how to reset the plugins folder,
   but I will look into this next. thank you!
