I used the cms Oxwall for 2 years and with respect to the other CMS is pretty good, but there is an issue that should resolve for the next version and the problem of sending emails, many people complain that your server stops sending and the cause is nothing more than a table in the database called -ow_base_mail-that within it has a field called -SentTime- which is what tells the exact time Oxwall they must leave the post, causing this great problem, as there are always synchronized and php server, or do not have cron enabled or time zone is not the same server, even hidden reasons unknown to me... Anyway would be nice to remove this field or a variant thereof which is not so dependent on the synchronization with the server and send mails even with hours spent... It's quite annoying to be asking for help on the same to the webmasters, which even so many times does not solve the problem ...
