WP 4.0 doesn't work when WooCommerce 2.2.2 is enabled

ok so ive rolled back to 3.9.2 and now i have the same issue, my site is completely blank whenever WooCommerce is activated!!

Any ideas much appreciated!

The WooCommerce alone cannot cause this issue.
Remember that you may be using several plugins that depend on WooCommerce to work! Without WooCommerce… these other plugins will also be inactive.

So what you are saying is i should disable all other plugins other than WC and try?

i also remembered i updated WC to 2.2.2 in the weekend as well.. i will try figure out how to roll back to previous version and see if it helps.

Hi Claudio – where can i download older versions of Woo Commerce and is there any tutorials on how to install older versions via FTP?

Thanks

Not recommend installing older versions, because they are unsafe.
Disable plugin by plugin to discover what is really the culprit.

i will do that, is there a guide on how to install correctly via FTP? I will make sure i have the latest version.. i see the website says 2.2.3

Just look on the internet, has hundreds of tutorials teaching how to install plugins by FTP.

Im now running 2.2.3 and WP 4.0

Ive been playing around with all the plugins and dont seem to be getting anywhere but i see this error in the logs

PHP Fatal error: Cannot redeclare woocommerce_output_related_products() (previously declared in /home/wheyhous/public_html/wp-content/plugins/woocommerce/includes/wc-template-functions.php:1091) in /home/wheyhous/public_html/wp-content/themes/dt-the7/inc/mod-woocommerce/mod-woocommerce.php on line 87

Yep, your theme redeclaring the woocommerce_output_related_products().
The problem is in your theme.

i have the same problem with new update woocommerce and wordpress…i downgrade the version of the 2 program and same problem…why update kill my website ??

the same to me, i upgrade wordpress to 4, now I can’t use wc!!!

in forums and commented that the update to the current vercion of wowcommerce generates error that does not let in wordpress pless installed on GoDaddy and I get the 500 error in the browser and delete all the plugin to see if any of them generates the error cause , but still the problem ……. perciste current vercion installed, but clicking to activate a delay is generated and the browser error 500 and at this point even without satisfactory answer critical note and perform tests to increase memory 64 but the error persists

I had an issue with this when I first upgraded to 2.2. The problem was that the wc database update needed to complete. I think the solution ended up being disabling all other plugins, enablign wc, and letting the db update run.
