Support » Plugin: WordPress Download Manager » Breaks my site

  • I was using this plugin for a couple years without issue, but after updating it and updating to WP 4.7, every post that has the download shortcode is broken and returns a 500 server error. Please help me fix this, so I can continue using it.

  • After disabling all plugins, I discovered that the issue is with WPDM and W3 Total Cache. WPDM works with W3 Total Cache disabled, but posts where the WPDM shortcode is included results in a 500 server error when W3TC is activated. I want to keep using W3TC and WPDM, is there any solution to this problem?

    More than likely the problem is related to Ajax. Ajax will not work on static pages.

    However, I found several plugins combined that actually gave me high scores in Google Insights, GTMetrix, and Yslow (96, 100, 99) than with W3 Total Cache in any configuration possible.

    I personally use the combination of WP Speed Grades Lite, JS & CSS Optimizer, (sometimes Falcon too). Once I remove blogging functionality and all of the wordpress headers, minify the CSS & JS and use my own browser caching code in .htaccess (which you can actually cut from WTC before you disable it and paste it back in afterwards lol. Its lightning. Went from like 100 different HTTP requests down to less than 20 on one of my sites.

    Hummingbird is also a really good caching plugin. Have you tried simply disabling page caching on W3 Total Cache?

    You could try to go in and make exceptions for the pages that you use Download Manager on inside of W3TC to prevent those pages and tools from being cached.
