PrestaShop Upgrade Problem

[kerchingwebdesign]

We have a Prestashop shop on http://www.creosotesales.co.uk/shop/

 

This has run for the last 12 minths or so on version 1.4....

 

Last week the PayPal module gave up working.

 

Today we have updated the shop to the latest 1.5.... version.

 

Of course this has now sent it into a tailspin: We couldn't access any of the module files,

the checkout didn't pick up the carrier etc etc.

 

I was trying to fix these failures one by one and slowly making headway. Low and behold the shop then decides to generate a server error and all seems lost. The shop now just displays a server error message.

 

Any suggestions? I have a database backup taken with the 1.4.10 version so I assume this will bugger up the 1.5 version if I find some magical way back into the site?

 

Why are these shops so flaky?

Usually when updating it is good practice to run upgrade on local or test server to evade

situation like yours and when all looks fine on test server then is safe to run upgrade to live website.

Especially on major upgrades like 1.4 to 1.5. And there are couple of issues that can happen

like incompatible modules or theme.

 

To see what causing that 500 error turn debug mode on change code in config/defines.inc.php to

/* Debug only */
define('_PS_MODE_DEV_', true);

 

and you should get more information about error.

Also you could delete .htaccess file if it causing trouble.

 

Also here are some tips

PrestaShop is not unstable, there are many thousands of stores that are running and updating their stores just fine.

 

From your post it seems that you upgraded a live shop without a trial upgrade. (I hope I am mistaken)

 

I take this from the official documentation

 

"You should never update your online shop right away. The upgrade tool can fail in some situations, and you might not be able to revert to the previous version.

 

The safest way is to have an exact copy of your shop available, either on your local computer or in another folder of your web server. It should contain all your products, categories, themes, modules, translations, settings, etc.

 

 

Make a trial upgrade on that copy of your shop. Once the upgrade is done, browse your front- and back-office thoroughly to make sure that everything is as expected."

 

This is in a red background screaming IMPORTANT in the Upgrade guide. http://doc.prestasho...ting+PrestaShop

 

There should be no reason that your website is down due to an upgrade. If done properly, you would know exactly what the errors are before you upgrade your live site. This is why we make it red on our manual, this is why there are hundreds of posts on the forum saying the same thing.

 

I don't understand when you say, "some magical way to back up" site. There is no magical way. You back up your database and you back up your PrestaShop files. It's not magic, it's good practice.

 

If I understood this incorrectly and you did in-fact have the backup of your last working PrestaShop database and files before the upgrade.

-Then the best suggestion is to revert to your backup before you did the upgrade.

-Make a trial upgrade on a test/dummy subdomain or localhost as detailed on the PrestaShop Documentation provided.

-If you have errors during the upgrade and need hep figuring them out, post them on the forum and we will do our best to help you.

 

 

 

 

Why are these shops so flaky?

 

Was this is your 1st post for a store you've been with for a whole year? I don't consider that flaky at all. We all understand it is frustrating when things do not go as planned, but this post does not leave much room for support at all.

 

We are here to help, and many great community members take time out of their day to help merchants just like you. This Topic Title and post almost seems like it discredits all that PrestaShop has done for your store for the 12 months, and also our community members who volunteer and work so hard helping merchants find their way towards a successful ecommerce store.

 

EDIT: I changed the topic title and moved it to Upgrading PrestaShop section of the forum.

How can you say that when so many, including myself, cannot upgrade from previous versions without a variety of errors? That doesn't sound stable to me. I've tried twice from 1.4.8.2 (4 times if you count trying both auto and manual methods), two different 1.5x final versions, and my shop ended up broken both times. And yes, I backed up my shop, so I lost nothing more than my time and maybe a few sales. I've decided not to try again until the error reports here are virtually none, not even to 1.4.10.
