I'm a bit confused now...
This is what K2 writes to me:
"I strongly disagree with Peter. His comment "I'm not sure I appreciate and want to keep having to work around issues K2 caused when it changes things which are already non-Joomla standard ways of doing things" is insulting and it's also confusing. Well, boo-hoo. We deal with third party extensions all the time. We don't go trashing the other developers, even if they're bad. Cause in the end, what matters is that the user/customer gets the job done.
I mean, is there like a "non-Joomla standard ways of doing things" for outputting text in a document? If he didn't understand the issue in the first place, he should say so.
Now, if you want to have your emails parsed by his plugin - which BTW should be smarter to perform a regex at the whole <a> element - you should probably re-order that plugin last. Updating K2 may have changed the order of some plugins. Worse case scenario, if you use a link type extra field, switch to plain text field. That should make it simpler for the plugin to grab the email address and convert it to an obfuscated link. "
I tried to reorder the plugins, but same result.
I don't know how to code, so I'm a bit lost here 🙁
