 * That message is related to the [wp-spamshield plugin](https://wordpress.org/plugins/wp-spamshield/),
   which was closed in October of 2017. Given that the plugin is no longer supported,
   I suggest disabling it and replacing it with something that is currently maintained,
   such as [Akismet Anti-spam](https://wordpress.org/plugins/akismet/).

 * Thank you so much. 
   I hadn’t noticed other similar messages. this one is everywhere:**
   Warning**: Trying to access array offset on false in **/home/allowdig/exchangetheatre.
   com/wp-content/plugins/wp-word-count/public/class-wpwc-public.php** on line **
   123**And this one:**Notice**: ob_end_flush(): Failed to send buffer of zlib output
   compression (1) in **/home/allowdig/exchangetheatre.com/wp-includes/functions.
   php** on line **5420**Thanks a lot for your time

 * The former comes from a plugin called “wp-word-count” which has not been in the
   WordPress repository since 2024 for security reasons. I would recommend removing
   the plugin.
 * The last message cannot be clearly attributed. This can be caused by various 
   plugins. Clarify the first two cases first, and then perhaps this will also be
   resolved.

 * Thanks again, both of you,
   The only left now is **Notice**: ob_end_flush(): Failed
   to send buffer of zlib output compression (1) in **/home/allowdig/exchangetheatre.
   com/wp-includes/functions.php** on line **5420**It appears under every box for
   an embedded page (for examples I have a timeline with clickable previews-boxes
   of other pages on the same website)

 * This may be caused by another plugin you have activated. Or even your theme.
 * Deactivate all plugins to test. If it is still there, switch to a standard theme.
 * If you are unsure about this, create a backup of the project beforehand.
