I was having major trouble with permalinks.
I'm used to Drupal which, in my humble opinion, makes pages names, changing page names, pretty URLs, etc. very easy. Anyways, I am running my company's "legacy" website, which was developed 3 years ago on WP.
I installed custom permalinks, but when I activate, I get an error message:
Parse error: syntax error, unexpected $end in /home/example/public_html/wp-content/plugins/custom-permalinks/custom-permalinks.php on line 175
Now, every time I get this, I delete the .php file from the plugins directory and when I reinstall and activate, I get the same error message, just on a different line. i.e.- this one is line 175, the last one was line 504 and the one before that was line 108.
