SELinux is preventing /usr/sbin/httpd from 'write' accesses on the file /var/www/html/wordpress/wp-content/plugins/akismet/akismet.php.

*****  Plugin httpd_write_content (92.2 confidence) suggests  ****************

If you want to allow httpd to have write access on the akismet.php file
Then you need to change the label on '/var/www/html/wordpress/wp-content/plugins/akismet/akismet.php'
Do
# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/wordpress/wp-content/plugins/akismet/akismet.php'
# restorecon -v '/var/www/html/wordpress/wp-content/plugins/akismet/akismet.php'

*****  Plugin catchall_boolean (7.83 confidence) suggests  *******************

If you want to unify HTTPD handling of all content files.
Then you must tell SELinux about this by enabling the 'httpd_unified' boolean.
Do
setsebool -P httpd_unified 1

*****  Plugin catchall (1.41 confidence) suggests  ***************************

If you believe that httpd should be allowed write access on the akismet.php file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
