Title: Woo Commerce PHP error? Please Help!! Last modified: August 21, 2016 --- # Woo Commerce PHP error? Please Help!! * Resolved [herbsolutions089](https://wordpress.org/support/users/herbsolutions089/) * (@herbsolutions089) * [13 years, 1 month ago](https://wordpress.org/support/topic/woo-commerce-php-error-please-help/) * I have woo commerce 1.5.4 installed on my site naturalherbalsolutions.net. Over the weekend, through no interference of my own something happened. Now When I visit the site I get this message: * Warning: session_start() [function.session-start]: open(/tmp/sess_d90f1162fd7f3566680d702ac48605c1, O_RDWR) failed: No space left on device (28) in /home/natur104/public_html/herbal/ wp-content/plugins/brokenwoocommerce/woocommerce.php on line 79 * Warning: session_start() [function.session-start]: Cannot send session cookie– headers already sent by (output started at /home/natur104/public_html/herbal/ wp-content/plugins/brokenwoocommerce/woocommerce.php:79) in /home/natur104/public_html/ herbal/wp-content/plugins/brokenwoocommerce/woocommerce.php on line 79 * Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /home/natur104/public_html/ herbal/wp-content/plugins/brokenwoocommerce/woocommerce.php:79) in /home/natur104/ public_html/herbal/wp-content/plugins/brokenwoocommerce/woocommerce.php on line 79 * Warning: Cannot modify header information – headers already sent by (output started at /home/natur104/public_html/herbal/wp-content/plugins/brokenwoocommerce/woocommerce. php:79) in /home/natur104/public_html/herbal/wp-includes/pluggable.php on line 881 * Warning: Unknown: open(/tmp/sess_d90f1162fd7f3566680d702ac48605c1, O_RDWR) failed: No space left on device (28) in Unknown on line 0 * Warning: Unknown: Failed to write session data (files).

So I know it’s woocommerce that is causing it. I don’t know how to fix this error. When I enable woocommerce again (having made 0 changes) I get this error right at the top of the dashboard:** * Warning: session_start() [function.session-start]: open(/tmp/sess_f8839191a511576ed9579d150ea0d428, O_RDWR) failed: No space left on device (28) in /home/natur104/public_html/herbal/ wp-content/plugins/brokenwoocommerce/woocommerce.php on line 79 * Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /home/natur104/public_html/ herbal/wp-content/plugins/brokenwoocommerce/woocommerce.php:79) in /home/natur104/ public_html/herbal/wp-content/plugins/brokenwoocommerce/woocommerce.php on line 79 * Warning: Cannot modify header information – headers already sent by (output started at /home/natur104/public_html/herbal/wp-content/plugins/brokenwoocommerce/woocommerce. php:79) in /home/natur104/public_html/herbal/wp-includes/option.php on line 563 * Warning: Cannot modify header information – headers already sent by (output started at /home/natur104/public_html/herbal/wp-content/plugins/brokenwoocommerce/woocommerce. php:79) in /home/natur104/public_html/herbal/wp-includes/option.php on line 564 * Perhaps some file was corrupted or deleted? I checked with my host (lunarpages) and they say the problem is on my end. I’m hesitant to update woocommerce since our versions were locked when this website was built. I was told that making such changes could cause coding errors on the site. Where should I start trying to figure this out? Any help at all would be GREATLY appreciated. I’m the definition of novice when it comes to these matters but I am more than willing to learn and will do whatever research it takes to implement your suggestions and of course report back here.

It’s worth checking how much data is in your account to see if that’s the problem. * [Pioneer Web Design](https://wordpress.org/support/users/swansonphotos/) * (@swansonphotos) * [13 years, 1 month ago](https://wordpress.org/support/topic/woo-commerce-php-error-please-help/#post-3709392) * Or more likely this: * [http://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F](http://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F) * [tiaanswart](https://wordpress.org/support/users/tiaanswart/) * (@tiaanswart) * [13 years, 1 month ago](https://wordpress.org/support/topic/woo-commerce-php-error-please-help/#post-3709410) * I think you have a plugin installed (might be the theme you are using as well) that is trying to either redirect or re-declare the header. * I would advise you switch themes to Twenty Twelve and then activate the plugin again to see if the issue is with the theme or the plugin. If it still fails then please contact the support team at WooCommerce. * Thread Starter [herbsolutions089](https://wordpress.org/support/users/herbsolutions089/) * (@herbsolutions089) * [13 years, 1 month ago](https://wordpress.org/support/topic/woo-commerce-php-error-please-help/#post-3709478) * Thanks guys I appreciate the fast and helpful responses! I had just started reading the faq that seacoast linked to but when I logged on to the site to explore my options it was inexplicably working. As I said I’m no expert but it seems that maybe my host was the problem as catacaustic suggested. I made no changes since last night and today there is no error message. I’ll get in touch with lunarpages to see what I can find out. Viewing 4 replies - 1 through 4 (of 4 total) The topic ‘Woo Commerce PHP error?
