Disabling mod security using these .htaccess commands:
<ifmodule mod_security.c="">
SecFilterScanPOST Off
</ifmodule>
and
<ifmodule mod_security.c="">
SecFilterEngine off
</ifmodule>
<ifmodule mod_security2.c="">
SecFilterEngine off
</ifmodule>
So I had to edit my whitelist.conf here:
/usr/local/apache/conf/modsec2/whitelist.conf
and you added
<locationmatch "="" post.php"="" wp-admin="">
SecRuleRemoveById 300015 3000016 3000017
</locationmatch>
<locationmatch "="" admin-ajax.php"="" wp-admin="">
SecRuleRemoveById 300015 3000016 3000017
</locationmatch>
<locationmatch "="" page.php"="" wp-admin="">
SecRuleRemoveById 300015 300016 300017
</locationmatch>
Exemple WP:
<locationmatch "="" post.php"="" wp-admin="">
SecRuleRemoveById 300015 300016 300017 950907 950005 950006 960008 960011 960904
