503 Service Unavailable Error After Switching Litespeed Rails Site From Production Mode To Staging Mode

Earlier I switched one of the Litespeed web server virtual hosts from production mode to staging mode and after gracefully restarting rails was receiving a 503 Service Unavailable error. Initially I thought that maybe Litespeed had to be restarted completely instead of just a graceful restart but that produced the same results. Below I describe the errors including errors in the Litespeed logs as well as how to resolve the issue which ended up being a silly mistake on my part.

The following article is a follow up to an article written on 01-19-201 and titled Sync iPhone Using Bluetooth With Windows 7 Computer.

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7680 bytes)

I recently reinstalled CentOS on a server for a client and then proceeded to install their WordPress web site on the fresh install of CentOS Linux. After working through various minor issues the WP site was up and functioning without issue but after a week or so they contacted me to let me know that they could no longer view items in their FAQ system via the WordPress administration site. The FAQ system is a WordPress plugin called FAQ Builder and is a great little system for frequently asked questions. Below I describe the error received when attempting to access the FAQ Builder admin and what I did to resolve the issue.

WordPress: Unable To Upload To The Media Library After Moving Servers

I recently moved a WordPress site from one location on a server to another location on the same server for a client. Everything seemed to work fine after following the directions in this article I had previously published. That article was specifically published for changing the domain that points to the WordPress site which could include simply changing the domain only or actually moving the site to a new server or new location on the same server and a new domain. If you are performing the second of those two options you may also need to update the “upload_path” depending on the configuration of the new server and if the paths are the same as they were on the initial server the WordPress site was installed on.

SVN Checkout Error: Malformed Network Data; Using TortoiseSVN or SVN CLI

I recently upgraded the Project Management Software, which happened to be Redmine, for a company and after the upgrade I received some complaints regarding SVN not functioning properly. I initially thought there is no way that the upgrade caused an issue with SVN since SVN and Redmine are completely separate however you can browse the SVN repositories from within Redmine. Below I describe the error in more detail including an image of the error from TortoiseSVN, what I did to resolve the issue, and another possible resolution if your issue is different than the one mentioned in this article.
