PHP 7.1 Compatibility Error

HI,

I did a PHP 7.1 Compatibility Test and I found the following error (not a warning, it’s an error):

FILE: wp-content/plugins/tablepress/views/view-about.php
——————————————————–
FOUND 2 ERRORS AFFECTING 2 LINES
——————————————————–
185 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0; Use mysqli instead
186 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0; Use mysqli instead
——————————————————–

Furthermore the following warnings appear:

FILE: /wp-content/plugins/tablepress/libraries/excel-reader.class.php
———————————————————————
FOUND 0 ERRORS AND 2 WARNINGS AFFECTING 2 LINES
———————————————————————
222 | WARNING | Method name “OLERead::__readData” is discouraged; PHP has reserved all method names with a double underscore prefix for future use
240 | WARNING | Method name “OLERead::__readPropertySets” is discouraged; PHP has reserved all method names with a double underscore prefix for future use
———————————————————————

Can you fix it?

Thanks in advance,

Alex
