Cannot modify header information

    I know there are lots of people who had the same problem but all the solutions I found, didn’t seem to work. I’m getting the following message:

    Warning: Cannot modify header information – headers already sent by (output started at /var/www/vhosts/okashinederland.com/httpdocs/index.php:2) in /var/www/vhosts/okashinederland.com/httpdocs/wp-includes/pluggable.php on line 1207

    This happens ONLY when I click on ‘Inspiration Tuesday’ under ‘blog’. I don’t really get it. I’ve tried to disable and enable the plugins and checked different .php files for extra spaces, etc. But nothing helped.

    Any suggestions?

    I’ve tried that, but there are no blank lines or spaces in the code. In fact, nothing seems off in the code

    If that did not help, then try:
    – Flushing any caching plugins you might be running, as well as server and/or browser caches. Also, any op cache or content network cache, as well as Cloudflare, clear those caches.
    – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
    – switching to the unedited default Twenty Fifteen theme for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).

    I’m now getting the following: 
    Fatal error: Cannot redeclare wp_cache_add() (previously declared in /var/www/vhosts/okashinederland.com/httpdocs/wp-includes/cache.php:24) in /var/www/vhosts/okashinederland.com/httpdocs/wp-includes/formatting.php on line 29
