wordpress deprecated message

I’m working with this parameters:
· Website: https://reptesmuntanyencs.cat
· TablePress: 1.10
· TablePress (DB): 39
· TablePress table scheme: 3
· Plugin installed: 2017/03/06 17:25:11
· WordPress: 5.3.2
· Multisite: no
· PHP: 7.3.7
· mysqli Extension: true
· mySQL (Server): 5.6.44-cll-lve
· mySQL (Client): 5.6.44
· ZIP support: no
· UTF-8 conversion: yes
· WP Memory Limit: 40M
· Server Memory Limit: 256M
· WP_DEBUG: true
· WP_POST_REVISIONS: true

When I create an entry, page or table I get a message like this:

Deprecated: strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior in /home/cv7chp5yps3n/public_html/wp-content/plugins/tablepress-responsive-tables/libraries/plugin-update-checker.php on line 851

I haven’t no problem with this because I work normally, but I don’t know what can I do to miss this message.

Best regards
