If your wordpress site is suddenly displaying garbage (a.k.a. someone elses pages) then you’ve been hacked. If you log in as administrator you’ll notice that your content should all be there and intact.
What they have done is modified your htaccess file.
To quickly restore your site to its’ former glory, I recommend simply:
- add the Bulletproof plugin in WordPress.
- Generate a sucure htaccess file (using the plugin)
- Select each option one by one and activate (enable) them all.
Your site should be back up and running normally.
As listeners to the podcast know I like VMWare products a lot. Although I use vSphere ESXi servers mainly, I routinely use their Workstation product to create VMs (virtual machines) to test things prior to trying them out on client’s systems.
I noticed that a Windows 8.x VM took a long time to shutdown. I thought it was that one VM at first until I found another VM running Windows 7 that had the same issue. I investigated and came up with a solution. Here’s how I fixed the problem.
Edit this file on the computer running the VMWare Workstation:
Add these lines to the end of the file:
prefvmx.minVmMemPct = “100”
mainMem.useNamedFile = “FALSE”
mainMem.partialLazySave = “FALSE”
mainMem.partialLazyRestore = “FALSE”
The simplest way to mount an ISO file within Winodws 7 32bit is to get Microsoft’s free utility.
According to Microsoft’s site “This utility enables users of Windows XP, Windows Vista, and Windows 7 to mount ISO disk image files as virtual CD-ROM drives.”
Sometimes it`s necessary to point out specific products. This is a great time to address the question of viruses and malware fighting. Get yourself a good physical firewall and make sure your computers are running an anti-virus. Listeners and clients ask me what anti-virus software I use and/or recommend.
If you need a quick check of your systems I`ve compiled a list for you (in no particular order):
- Microsoft Safety Scanner (http://www.microsoft.com/security/scanner)
- Eset Online Scanner (http://www.eset.com/us/online-scanner)
- Malwarebytes (http://www.malwarebytes.org)
I usually recommend and resell:
- AVG (http://www.avg.com) – Note: AVG have a nice management console for Business environments.They now offer a cloud based solution as well.
These are the ones that I found worked well. Protection from any or all of these may not protect you from all possible viruses or intrusions. I can`t guarantee the same success that I`ve experienced with them.
Exchange 2010 Repair IT Article – By Bob Pellerin
Problem: The server had a “rough night” and needed to be relocated to a new host after a few unexplained hangs. Priliminary tests after the move were positive. Email got in and out from internal and external sources. We noticed that the public database was “unmounted”. Trying to mount it resulted in this message:
Couldn’t mount the database that you specified. … An Active Manager operation failed. Error Operation failed with message: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-515)
For all those of you out there that recently completed the migration from earlier version, you may want to note that version 5.5.0a of VMWare’s vSphere ESXi has been released.
The latest build numbers are as follows:
VMware vCenter Server™ 5.5.0a | 31 OCT 2013 | Build 1378901
vCenter Server Appliance 5.5.0a | 31 OCT 2013 | Build 1398493
Although these updates are considered minor, you should check to see if the fixes they bring to the previous builds are relavent in your environment.
Personal note: I’ve had a great experience going from VMWare vSphere ESXi 5.1 to 5.5. The only minor issue I’ve seen so far is an alert that is triggered incorrectly.

We`re getting ready to release our first podcast! Stay tuned!
