I was taking photos when suddenly my Canon PowerShot SD 1300 IS IXUS 105 read "Lens error. Will shut down automatically. Restart camera." Then the screen went blank. The lens will not retract. I cannot do anything other than turn the camera back on and get the same message. I've never had this problem before.

Here's a video covering troubleshooting steps for this problem.
and here's a page summarizing the above steps.

"Lens error, restart camera". Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...Here's an article and here's a video that shows some things that you can try that may (or may not) correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them.

You may have gotten dirt or dust into the lens mechanism. Sometimes an air cleaner can help the situation.

hi if your lens looks bad like crooked, then you have to send to canon. They don't sell lens unit to local repair shop. but not serious problem (lens repairable) then bring to local repair shop. canon will charge you about $135, local repair shop would charge you $65 Thanks and good luck with you!

something has malfunctioned in the lens motor itself, unfortunately this means that your going to have to take the camera into a repair shop or send it back to canon for repair.

It always comes because there is something loose inside the lens, such as a screw. These articles maybe helpful for you: Lens error, E18 error and turn the power off and on again Good luck

That is a problem you will need to go to fix at a Canon store or local camera store. It shouldn't cost more than $20.

So when its stuck you just push on the lens.
i know it sounds crazy, and it'll sound like you cracked it, but it really does unjam your camera!
try it!
