Wish I'd Known This Before Upgrading to WordPress 4.7

Upgrading to WordPress 4.7 with W3 Total Cache Installed

Yesterday was one of those days. You know, the kind of day when something routine that should take a couple of minutes, (or less), ends up taking hours out of your day. What did I do? I hit the button to upgrade my WordPress Website to WordPress 4.7. 90 seconds later I was looking at the white screen of death. My website was fine to the outside world, but I could not access the admin panel. 

Not one to panic, I figured a Google search would soon have me up and running again. There's no way I could be the only one with this problem. Wrong! After a good long time searching for a solution I decided nothing really fit my particular scenario and that I should call my hosting company and ask if this was a known problem. The Customer Service Person at A2Hosting was most helpful. In fact, if you're looking for a Hosting Company that offers top of the line customer service, check out A2Hosting. 

It turns out that it was the W3 Total Cache Plugin that was the problem. It needed to be removed and re-installed before the site was up and running again. He said he'd had lots of practice doing this yesterday and I was definitely not his first call!

Sooo... The moral of this story is, if you have W3 Total Cache installed, uninstall it and reinstall it before upgrading to WordPress 4.7. Deactivating may also work, but since I'm the one who spent way too long  dealing with the fall out of this failed upgrade, I'm going for not cutting corners on this one!

This particular solution worked for me for the particular scenario of having W3TC installed. The white screen of death is not exactly unheard of in the upgrading process on WP websites. The following article gives some pointers on what to do before upgrading to WordPress 4.7. Hindsight being what it is, I might have known what to look for sooner if I'd read this first!

Oh wow, thx for the heads up.  Just yesterday, I created a new site w/ 4.7 and hoping today to migrate the old site over (the site is just 8 pages, so hopefully it won't be a big deal.  I uploaded w3 after, so I didn't have a problem.

However, at some pt, I will be upgrade my main site, and I now know to be careful w/ this.  I've been afraid to upgrade it from the last one as I have a premium plugin that may not be compatible with it...and it's a plugin that generates income.  Will need to research that at the end of month.

Yes, those pesky plugins Debbie. They are almost always the reason an update fails. I included a link at the bottom of the post to "best practices" that might help before you upgrade your main site.

Thanks for the heads up, Denise. I will say this... to me WordPress has always been a mystery and difficult to navigate.

Yep. I definitely agree with that. I had a friend who always said you pay for your education. He didn't always mean money either!

Denise, oh, a frightful experience! I have a Wordpress site that is not hosted, persay, free and I won't be touching it. Unlike you, I wouldn't have anyone to call, as this one I signed up for and created myself many moons ago. And how nice of you to give us words of wisdom on avoiding the white screen of death. Is that what they actually term it??

.White screen of death is absolutely what they call it Gayle. No prizes for guessing that they "stole" the phrase from Microsoft's blue screen.. :)

Wow, I'm sure I would have had an almost heart attack also. Luckily (or not) I've had that happen before & the hosting company corrected it. I'll keep this info in the back of my mind just in case. Glad your up & running.

Denise Hamlin, Broker/Owner

You're right there Lyn. It was not a fun moment when it happened. I had to remind myself not to panic. :) I will be a lot more cautious in the future that's for sure!

For me the upgrade put a sidebar on my pages that was only intended for the blog posts. I couldn't figure out how to get rid of it and had to call in my Wordpress guru to fix it.

I always dread those "updates" and have learned to do them on a Sunday evening or some time when it's not critical should everything crash or be held hostage for hours.

Oh WOW! I didn't have that with this particular plug-in but, have had this kiss-of-death upgrade before and it's horrifying! Glad the customer service at A2Hosting was so wonderful - and see, you weren't alone in having this happen either! Thanks for sharing, Denise!
