It seems your web host hasn’t allowed you enough memory.
Try adding this to your .htaccess file:
php_value memory_limit 32M
The memory_limit is already 64MB 😉
It seems, 64 MB isn’t enough for your blog. Try a value of 96MB or 128MB with jdingman’s solution.
Adding the parameter resulted in a 500 Internal Server Error.
Removal of the offending line, resulted in a reactivated site, yet a blank screen.
Repair of all database files resulted in a working site again.

Nope, rebuilding the database files failed to solve all the problems. For example, the browser was trying to open or save comment.php when I wanted to save a modified comment. So I had to re-install. The server is slow in copying the files, so it is difficult to see how much the plug-ins and widgets have been wiped out.
The cPanel interface tells me it is copying the files over, though there are problems due to incomplete copying.
O.K. After about 2 hrs. back to about 97% normal.
Internal Server Error 500 may occure, when this parameter is not allowed. But it shouldnt result in that mess after removing the line again.
I will try to find solutions for even less memory usage.
The error msg fpor the sitemap file doesnt say that much. I have no idea what could be wrong. The generated sitemaps do follow the guidelines.
File copying errors and problems have nothing to do with the plugin. I guess there are problems with your server or hosting provider.
Talked with remote host tech support.
I had to change the parameter in the php.ini in /public_html, then copy php.ini to every directory AND subdirectory that has php files where I wanted the change to take effect. I also altered the memory parameter of the wp-config.php file.
The error message disappeared after all of that was done. I set all to 96MB.
“Just saying,” for an installation on a remote host, it would seem ill-advised to recommend adding the parameter to .htaccess
Good that you found a way to increase the memory_limit.
I wasnt sure if you are able to change php.ini or are allowed to use ini_set in wp-config.php, since the .htaccess soluton didnt work. So I didnt mention these ways. Thanks for your update.
