Thanks for the advice.
Thank your for your advice.
1. I can’t find the PHP.ini file
2. I tried the changes you suggested in the .htaccess file, but then I couldn’t log into WordPress.
3. I made the suggested change to the the wp-config.php file, but I got the same error message as before.
4. I’ve already tried contacting the host, but they haven’t replied.
I will try contacting the host again.
