Title: Sliders duplicating Last modified: August 21, 2016 --- # Sliders duplicating * Resolved [djones8520](https://wordpress.org/support/users/djones8520/) * (@djones8520) * [11 years, 10 months ago](https://wordpress.org/support/topic/sliders-duplicating/) * Hi * I’m having a weird issue that I can’t seem to figure out. I’m trying to get the default wordpress slider working. When I create the slider one shows up in the list and sort of works nicely. * The issue is whenever I update the slider multiple sliders are duplicated in the list and the slider becomes usable. The update never finishes and eventually timesout with a server error. When I go back to the list there are as many as 81 sliders duplicated. All have the same name and content (different shortcodes). They don’t all get instantly created. It takes roughly two minutes for all 80ish to have been created. * NOTE: While I was posting this, the issue occured while I was Publishing a slider. * Server error I receive: 502 – Web server received an invalid response while acting as a gateway or proxy server. * I’m not 100% sure, but I believe the php log associated with the issue is the two lines below. * ``` [21-Jul-2014 14:13:43 America/Los_Angeles] PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0 [21-Jul-2014 14:14:15 America/Los_Angeles] PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0 ``` * Below are a few other PHP warnings that I haven’t fixed yet, that may or may not be related to the issue. These warnings occur multiple days throughout the log at varying times throughout the log. * ``` [21-Jul-2014 21:07:53 UTC] PHP Warning: Division by zero in D:\home\site\wwwroot\wp-content\themes\startbox\includes\extensions\startbox-slideshows\startbox-slideshows.php on line 523 [21-Jul-2014 21:07:53 UTC] PHP Warning: Illegal string offset 'width' in D:\home\site\wwwroot\wp-content\themes\startbox\includes\extensions\startbox-slideshows\startbox-slideshows.php on line 527 [21-Jul-2014 21:07:53 UTC] PHP Warning: Illegal string offset 'width' in D:\home\site\wwwroot\wp-content\themes\startbox\includes\extensions\startbox-slideshows\startbox-slideshows.php on line 528 [21-Jul-2014 21:07:53 UTC] PHP Warning: Illegal string offset 'height' in D:\home\site\wwwroot\wp-content\themes\startbox\includes\extensions\startbox-slideshows\startbox-slideshows.php on line 528 [21-Jul-2014 21:07:53 UTC] PHP Warning: Illegal string offset 'width' in D:\home\site\wwwroot\wp-content\themes\startbox\includes\extensions\startbox-slideshows\startbox-slideshows.php on line 528 [21-Jul-2014 21:07:53 UTC] PHP Warning: Illegal string offset 'height' in D:\home\site\wwwroot\wp-content\themes\startbox\includes\extensions\startbox-slideshows\startbox-slideshows.php on line 528 [21-Jul-2014 21:07:53 UTC] PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'output' not found or invalid function name in D:\home\site\wwwroot\wp-includes\plugin.php on line 470 [21-Jul-2014 21:07:56 UTC] PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'output' not found or invalid function name in D:\home\site\wwwroot\wp-includes\plugin.php on line 470 ``` * Thanks for any suggestions.

If that doesn’t resolve the issue, try switching themes. * Thread Starter [djones8520](https://wordpress.org/support/users/djones8520/) * (@djones8520) * [11 years, 9 months ago](https://wordpress.org/support/topic/sliders-duplicating/#post-5118727) * I deactivated the plugins and the issue is still there. I’m a little nervous about switching the theme. What affect will switching the theme have on the site? That’s probably a newbie question, but I wasn’t the one that setup the theme for this site. * Thanks for the help. * Moderator [Jose Castaneda](https://wordpress.org/support/users/jcastaneda/) * (@jcastaneda) * THEME COFFEE MONKEY * [11 years, 9 months ago](https://wordpress.org/support/topic/sliders-duplicating/#post-5118792) * Gotcha. I would contact the person who setup the theme then because it sounds like it is theme related if all plugins are deactivated and the issue is still there. If the theme is in the [repo](http://wordpress.org/themes/) then be sure to post in that theme’s forums. 🙂 * Thread Starter [djones8520](https://wordpress.org/support/users/djones8520/) * (@djones8520) * [11 years, 9 months ago](https://wordpress.org/support/topic/sliders-duplicating/#post-5118812) * Yeah, it looks like the theme isn’t updated anymore. I suspect it may have a bug with wordpress 3.9.1. I’m going to change this to resolved, since I’m pretty sure it’s the theme. Our temporary solution is another slider plugin, but we’ll change the theme eventually. * Thanks for the help.
