I can’t upgrade.

Try one (or all) of these:

1. Try adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '64M');

2. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 64M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

3. If you don't have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 64M

4. Talk to your host.

I did the first one. I need to look into items 2 & 3 now. I tried editing http.php since that’s what the error message said, but here’s what’s on line 1327 and I don’t see what it has to do with anything:

$parts = explode(“\r\n\r\n”, $theResponse);

Edited .htaccess, got this message when I went to home page and had to revert:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

And I can find no php.ini file for that domain.

All I had to do was deactivate the plugins while doing the upgrade. It was that simple.
