    Hello,

    Great plugin, i like that the equation is text based instead of using images.

    I have come across a problem when using WP-Katex on a site that has a theme that uses the wpbakery visual composer plugin. The problem occurs when i insert an equation into a page, it throws up this error:

    Warning: Invalid argument supplied for foreach() in /home/simonlaw/public_html/dev/wp-content/plugins/js_composer/include/classes/core/class-vc-base.php on line 345

    Warning: Cannot modify header information – headers already sent by (output started at /home/simonlaw/public_html/dev/wp-content/plugins/js_composer/include/classes/core/class-vc-base.php:345) in /home/simonlaw/public_html/dev/wp-includes/pluggable.php on line 1173

    I am seeing this when i preview the page after inserting this code:
    [latex]A= -ln(\frac{Ii}{Io})[/latex] [1]

    One thing that is weird is that it works if the code is up around the top of the page, but further down, i get the above error.

    The theme i am using is trizzy – https://themeforest.net/item/trizzy-multipurpose-woocommerce-wordpress-theme/8724702

    Any ideas on what is causing the conflict?
    Cheers

    WP-KaTeX should not be modifying any headers. It’s a very simple plugin that replaces the LaTeX shortcodes with a bit of JavaScript that renders the equation.

    I will try to reproduce this later, but I don’t think I am able to, as your plugin and theme are not free.

    @mrlaw, i think i can to help you solve this problem.

    The problem I was having seems to have resolved itself. Both the theme and Visual composer have been updated, so it looks like something in those updates has fixed it.

    Cheers
