The dreaded double dash issue is back in wordpress. This issue is where wordpress automatically reformats two dashes, into a single long dash. It needs to be removed in blogs like this ome, where many of the commands you see are infact double dashes. This is the quick fix for it.
Login into your site
Go to: Dashboard
Select Theme Editor
Scroll to the bottom of the page and paste
add_filter( ‘run_wptexturize’, ‘__return_false’ );
The issue is fixed
Make sure the ‘ symbol above is correct, if it is the apostrophe that slants forward it will not work. it has to the be the apostrophe character that is straight up/down
You will probably need to do this everytime you update your wordpress theme. So bookmark this page and come back when you need to fix it next time.
