Title: Errors Last modified: August 21, 2016 --- # Errors * Resolved [vennardk](https://wordpress.org/support/users/vennardk/) * (@vennardk) * [12 years, 10 months ago](https://wordpress.org/support/topic/errors-45/) * When I installed the plugin I received the following error: * The plugin generated 2 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin. * When I attempt to upload a csv file I receive this error: * Warning: Cannot modify header information – headers already sent by (output started at /home/content/58/11637758/html/wp-content/plugins/sports-rankings-lists/wp- ranking.php:286) in /home/content/58/11637758/html/wp-admin/async-upload.php on line 32 51 * I’m positive it has nothing to do with file format and/or playing the correct data in the correct columns. Any other thoughts or ideas? * [http://wordpress.org/plugins/sports-rankings-lists/](http://wordpress.org/plugins/sports-rankings-lists/) Viewing 11 replies - 1 through 11 (of 11 total) * Thread Starter [vennardk](https://wordpress.org/support/users/vennardk/) * (@vennardk) * [12 years, 10 months ago](https://wordpress.org/support/topic/errors-45/#post-4041193) * I attempt to add a list category: * Warning: Cannot modify header information – headers already sent by (output started at /home/content/58/11637758/html/wp-content/plugins/sports-rankings-lists/wp- ranking.php:286) in /home/content/58/11637758/html/wp-includes/class-wp-ajax- response.php on line 129 * I attempt to publish a list: * Warning: Cannot modify header information – headers already sent by (output started at /home/content/58/11637758/html/wp-content/plugins/sports-rankings-lists/wp- ranking.php:286) in /home/content/58/11637758/html/wp-includes/pluggable.php on line 875 * Not trying to spam.

If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin. * I ignored the list category but still received the above error messages. * The CSV file had no headers. I created my own file and then I also used the sample file you provide (great idea to offer this BTW) * I apologize, I’m not sure what a feed issue is. I’ll try to wait patiently while you fix it. 🙂 This could be a very handy tool as no other plug-ins fulfill my need to rank players. I appreciate your hard work! * Plugin Author [kutu62](https://wordpress.org/support/users/kutu62/) * (@kutu62) * [12 years, 10 months ago](https://wordpress.org/support/topic/errors-45/#post-4041388) * okay its fixed – RSS and sitemap errors gone.. just had to remove white space in file. * Thread Starter [vennardk](https://wordpress.org/support/users/vennardk/) * (@vennardk) * [12 years, 10 months ago](https://wordpress.org/support/topic/errors-45/#post-4041430) * Better. No header errors anymore. I edited “sports-rankings-lists/import_players. php” by overwriting the comma to a semi-colon when reading while importing a list (I use open office). * However, after using the ranker short code on a post, I receive the follow error. Please note that line 176 and line 193 error appears a lot more times in that order. I didn’t count but I’m assuming one of each error for each player in the list (200+). * Any thoughts or ideas? * Warning: Invalid argument supplied for foreach() in /home/content/58/11637758/ html/wp-content/plugins/sports-rankings-lists/wp-ranking.php on line 150 * Warning: Invalid argument supplied for foreach() in /home/content/58/11637758/ html/wp-content/plugins/sports-rankings-lists/wp-ranking.php on line 176 * Warning: Division by zero in /home/content/58/11637758/html/wp-content/plugins/ sports-rankings-lists/wp-ranking.php on line 193 * Warning: Invalid argument supplied for foreach() in /home/content/58/11637758/ html/wp-content/plugins/sports-rankings-lists/wp-ranking.php on line 176 * Warning: Division by zero in /home/content/58/11637758/html/wp-content/plugins/ sports-rankings-lists/wp-ranking.php on line 193 * Warning: Invalid argument supplied for foreach() in /home/content/58/11637758/ html/wp-content/plugins/sports-rankings-lists/wp-ranking.php on line 176 * Warning: Division by zero in /home/content/58/11637758/html/wp-content/plugins/ sports-rankings-lists/wp-ranking.php on line 193 * Plugin Author [kutu62](https://wordpress.org/support/users/kutu62/) * (@kutu62) * [12 years, 10 months ago](https://wordpress.org/support/topic/errors-45/#post-4041433) * why change plugin file from comma to ; ?? * **delete the plugin from your server ** * download and install again * If errors persist you’ll need to disable all plugins – then enable the ranker and you should not have errors anymore – * then enable you other plugins one at a time until you find the conflict – * let me know which plugin has a conflict and I’ll look at it. * I tested this plugin on three servers / installed with various themes and plugins and it works fine – so the issue is isolated to your install.

I went back to open office and confirmed it was saved as a .csv. So the quickest fix was for me to tell the importer to look for a “;” instead of a comma. I included that information in my last post, just in case there was a chance it might have messed something else up. * I disabled all plugins that do not come with a clean install. Still having the same issues. * Rankings are not working on the front end (user side) but do import nicely into the backend (admin side). * I’ll try to round up more details tonight. * Plugin Author [kutu62](https://wordpress.org/support/users/kutu62/) * (@kutu62) * [12 years, 10 months ago](https://wordpress.org/support/topic/errors-45/#post-4041440) * hmm.. * should work fine.. * email me admin username and password to your website and I’ll take a look. * Also, send your apache logs – * Kurt at fantasyknuckleheads dot com * Plugin Author [kutu62](https://wordpress.org/support/users/kutu62/) * (@kutu62) * [12 years, 9 months ago](https://wordpress.org/support/topic/errors-45/#post-4041488) * This was a user error – plugin works fine – please see the screenshots if you have trouble using * [nicholasdeleo](https://wordpress.org/support/users/nicholasdeleo/) * (@nicholasdeleo) * [12 years, 4 months ago](https://wordpress.org/support/topic/errors-45/#post-4041528) * Hi, I get the same errors as the other user reported. * I havent’t found the solution, I can only see it was actually found. * Warning: Invalid argument supplied for foreach() in /web/htdocs/www.coinflipclub. it/home/wp-content/plugins/sports-rankings-lists/wp-ranking.php on line 150 Warning: Invalid argument supplied for foreach() in /web/htdocs/www.coinflipclub.it/home/ wp-content/plugins/sports-rankings-lists/wp-ranking.php on line 176 Warning: Division by zero in /web/htdocs/www.coinflipclub.it/home/wp-content/plugins/sports- rankings-lists/wp-ranking.php on line 193 Warning: Invalid argument supplied for foreach() in /web/htdocs/www.coinflipclub.it/home/wp-content/plugins/sports- rankings-lists/wp-ranking.php on line 176 Warning: Division by zero in /web/htdocs/ www.coinflipclub.it/home/wp-content/plugins/sports-rankings-lists/wp-ranking. php on line 193 * Could you please help me out, too? * Best Nicholas * Plugin Author [kutu62](https://wordpress.org/support/users/kutu62/) * (@kutu62) * [11 years, 12 months ago](https://wordpress.org/support/topic/errors-45/#post-4041536) * [@nicholasdeleo](https://wordpress.org/support/users/nicholasdeleo/) * The errors when uploading CSV is due to the CSV not being a “windows CSV” – you’ll see this option in MAC and Open Office. So when you save the file as CSV make sure you save the file as “MS Windows CSV” or “Windows CSV” – Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘Errors’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/sports-rankings-lists_ecf0f0.svg) * [Sports Rankings and Lists](https://wordpress.org/plugins/sports-rankings-lists/) * [Frequently Asked Questions](https://wordpress.org/plugins/sports-rankings-lists/#faq) * [Support Threads](https://wordpress.org/support/plugin/sports-rankings-lists/) * [Active Topics](https://wordpress.org/support/plugin/sports-rankings-lists/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/sports-rankings-lists/unresolved/) * [Reviews](https://wordpress.org/support/plugin/sports-rankings-lists/reviews/) * 11 replies * 3 participants * Last reply from: [kutu62](https://wordpress.org/support/users/kutu62/) * Last activity: [11 years, 12 months ago](https://wordpress.org/support/topic/errors-45/#post-4041536) * Status: resolved
