I found this code in the forums but it is not stripping the code:
181.224.134.27/~icd10mon/index.php?option=com_k2&view=itemlist&layout=tag&tag=EHR&task=tag&Itemid=425

The default intro text limit works fine: 181.224.134.27/~icd10mon/index.php?option=com_k2&view=itemlist&layout=category&task=category&id=83&Itemid=90

Hello Jeff,

If you are using wordlimit, then all HTML tags are being stripped, this means that the <script> tag is being stripped and the content of that script is being treated as plain text.

Thank you for the help.

How do I display the first 50 words of the introtext without the stripped code issue?

I would suggest using a different editor for introtext and fulltext or manually define an introtext using the read more button.
This way you won't have to use a wordlimit.

You can also use str_replace() - php.net/manual/en/function.str-replace.php in your template to strip the script altogether.

I fully agree, but this is a migrated website in which the previous webmaster did not tell the clients about the readmore feature. So there are 1566 k2-items that need to now show an "intro" on the blog layout page.

I saw other posts that other users said the wordlimit works but it shows code for me. Is there another way?

Yes with 1566 items, the manual method is surely out of the question.
You can try with the str_replace() method to completely remove that script from the introtext in your template overrides.

Would I have to list all the needles of code? Is there any code that you know would work that I can paste in?

Another option would be a database replace, where I insert a <hr id="system-readmore" /> after the first 50 words. I don't know how to do this but it may be another option....

Yes you could use an SQL script to manually insert the <hr id="system-readmore" /> but you will still need to keep entering the limit on newly created items.

If you use str_replace()
A more robust solution would be to use preg_replace - php.net/manual/en/function.preg-replace.php - to completely remove all
