    Can you try increasing the memory further?

    OK, that killed my site completely with a:

    Fatal error: Call to undefined function is_admin() in […]/wp-includes/vars.php on line 16


    Allright, I had to update WP 2.9.2 all over again — manually this time — and that solved the problem.

    I believe the error may have been caused because I made the memory size change to wp-settings.php of WP 2.9.1 (which I had on my PC) while I had automatically upgraded to WP 2.9.2 on the server, hence a mismatch.

    I have now synched WP on the server and on my PC to 2.9.2. In fact, I intend to ALWAYS do a manual upgrade of WP from now on. This way, I remember to keep both versions (server and PC) in sync.

    I am not sure but the auto upgrade of WP 2.9.2 may have copied wp-settings.php with the default 32M memory size — which reintroduced the original problem of not being able to edit a long post. I upsized the memory and I can now edit the long post again.

    Moral of the story: it’s probably best to manually upgrade WP (as well as the plugins, for that matter) if you do any changes on your PC first and then FTP the changes to your server. This way, you won’t auto upgrade WP on the server and forget to manually upgrade WP on your PC. Just my 2c.

    A question to the developers: wouldn’t it be a good idea to make the memory size a General or Miscellaneous Setting? Or else, upsize the default: 32M may not be enough?
