I've been running into this issue lately where I cannot save content in a CMS page if it contains the word 'Select' or any variant of the page. Whenever I try and save a page with the word 'Select in the content area it does the typical refresh but does not say that the page has been saved as usual and the content will revert back to whatever it was before the updated content was put in.

Also if it is a new page it will not create the page when you try and save.

I'm not entirely sure about this but it seems that it may be a copy and paste issue with the word select. I've tried hand writing small portions of code containing 'Select' and it will save sometimes.

I've also tried replacing the word select with anything else and it will save the page but when I try and add select back inside of magento it does not save the page.

The only workaround I have at the moment is to write the content directly into the database but this is not sufficient because our client needs to be able to update content as well.

Any ideas? Suggestions? 

Additional Information: Looks like I've found another set of words that won't save 'From Effect'
