FreieReferate

Thank you for your help! Here is the code of my first link: https://pastebin.com/BHLR4uQU

I use these plugins:
Breadcrumb NavXT
Contact Form Email
Jetpack von WordPress.com
WP Rocket
WP-PostRatings
WP-Pro-Quiz
Yet Another Related Posts Plugin
Yoast SEO

And my wordpress is on the newest version.

Hello Jeremy,

thank you for your help. But it doesn’t work. Everytime I use < or > (with or without spaces) I become the error. I tried to use \less and \gtr instead of < and >, but this also doesn’t work.

I use this plugin for years and everything was fine. For a couple of month the error appears. Maybe because of an update of jetpack? Or is there any known errors with other plugins? But I don’t use any plugins that change the content. Only plugins such Related Posts, Breadcrumbs, etc.

I love the plugin and in Germany a few people want to learn math on my site. It would be great if you can help me ??

Btw the error appears on every site in my math-Section, where I use < or >:

Ahh thank you for this tip ?? It works for me with this:

<?php echo do_shortcode(‘[CONTACT_FORM_TO_EMAIL id=”1″]’); ?>

from here: https://codex.www.ads-software.com/Function_Reference/do_shortcode

you can see the contact form in a hardcoded sidebar here: https://www.freiereferate.de/chemie

Thanks all again! ??

Okay, thank you for the tips! I’ll test it and ask my provider how I can change the permission for such a directory.

Okay, thanks for the tips! I’ll test it ??

here the screenshot. Now I can’t login in the admin-interface. The frontend is okay: https://imgur.com/XGliocP

Thank you for the tips! ?? WP_DEBUG is on false. I will test the changes in the file-permissions.

Thank you for your tips!

The error message is on the admin-interface. I tested the version 2.0.9. There was the same error. With version 2.0.7 there error disappeared!

All the time the plugin works in the user frontend perfect.
