 * These are the errors I’m getting:
 *     ```
       Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 in /home/nc/public_html/wp-includes/class-wp.php on line 202
   
       Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 in /home/nc/public_html/wp-includes/class-wp.php on line 201
       ```
   
 * Just lines and lines of that, and at the end it says:
 *     ```
       Warning: Cannot modify header information - headers already sent by (output started at /home/nc/public_html/wp-includes/class-wp.php:201) in /home/nc/public_html/wp-includes/functions.php on line 861
   
       Warning: Cannot modify header information - headers already sent by (output started at /home/nc/public_html/wp-includes/class-wp.php:201) in /home/nc/public_html/wp-includes/functions.php on line 862
       ```
   
 * This happens when I click on the Pages tab in my WordPress administration panel.
   I’m pretty sure I don’t have any corrupt files and I have tried reinstalling 
   my version of WordPress numerous times but I still get the same error. Does anyone
   have a fix for this?
