Hi, I am running Magento 2.0.4 in Plesk successfully and the site has been running fine. Today I updated my db to Maria db 10.1.14 from 10.1.13 and now I'm getting the error below and I cannot access the site at all. Does anyone know how to fix this? Thanks

Hello,

Rename the file:

pub/errors/local.xml.sample

to:

pub/errors/local.xml

It will make Magento show errors

Hi Stanislav,

Thanks for the reply. The error message I am getting now is;

Warning: SessionHandler::read(): open(/var/lib/php/session/sess_cvevqn06desuj80, O_RDWR) failed: Permission denied (13) in /var/www/vhosts/[site]/httpdocs/vendor/magento/framework/Session/SaveHandler.php on line 74

In the server update, i believe the php version was also updated. Also i can see 14 errors from the db

catalog_category_product_index_tmp
catalog_product_index_eav_decimal_tmp
catalog_product_index_eav_tmp
catalog_product_index_price_bundle_opt_tmp
catalog_product_index_price_bundle_sel_tmp
catalog_product_index_price_bundle_tmp
catalog_product_index_price_cfg_opt_agr_tmp

They all say "The storage engine for the table doesn't support check"

It looks like the web server/PHP no longer have permissions to read/write from the sessions storage (/var/lib/php/session/). How are you running PHP? As an Apache module or fastcgi/php-fpm?

Where do you see the database errors? On the same error screen?

Thanks for the update, when i change the permissions for the folder /var/lib/php/session/ the site loads up.

There is a Check and repair future within Plesk and that is producing the errors but im not sure if they are of any significance. I am running Apache with PHP version 7.0.6 as FPM. It seems its a permissions issue. Im not sure why this has suddenly happened, do you have any suggestions for this?

[oaknfold]

It appears that Plesk changed the permissions on the sessions folder. This has been updated and now working correctly.

• After upgrading system PHP, the /var/lib/php/session directory could get wrong permissions and PHP sites could work incorrectly. (PPPM-4558)

However the permissions now are set to 1733. Is this correct?

Thank you very much.

I appreciate your help.

I had this issue and was caused by file permission. Just rest files permission. I am hosting my magento with Cloudways, and they have the option to reset permission from the hosting control panel.

Sorry to bump this.

The error I get is this:

Warning: ini_set(): Cannot find save handler 'memcached' in ... /vendor/magento/framework/Session/SessionManager.php on line 536

Any clue?

I have this error. Where is the pub folder? Can't see it in the root
