Your are currently running PHP 5.2.17. Please contact your hosting provider to request that they update your PHP. * Also a PHP dev who does WP stuff, I haven’t run 5.2 in years.

The exact line at the host is: * The PHP System Default Version is 5.4 * But MyBookTable has stopped working, nothing showing in my drop down menu where I had books, and no books in the page where they were displaying before, and no featured books widget which I also had in the sidebar. * Developers: Where do I download the previous version while you work on this issue? * Thanks. * [KSJones](https://wordpress.org/support/users/ksjones/) * (@ksjones) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748797) * I am having the exact same problem as Member mcshanecomm and KProvance. Mine says: “PHP Out of Date – MyBookTable requires at least PHP 5.3.9. Your are currently running PHP 5.2.17. Please contact your hosting provider to request that they update your PHP.” I have lost My Book Table and all the books on it! I still have the ‘Pro Upgrade’ for My Book Table though, but it can’t run without the basic. So, I re-installed the basic, but I am still getting the PHP message to update. * Plugin Author [Thomas Umstattd](https://wordpress.org/support/users/neovita/) * (@neovita) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748802) * We will have a fix out in the next version. * It is just a misfiring error code. Nothing is broken. * Plugin Author [zookatron](https://wordpress.org/support/users/zookatron/) * (@zookatron) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748803) * Wow, I did not expect this to happen, I apologize for this. I added this since we had a lot of people on old PHP versions who were updating the plugin, and unfortunately WordPress does not check for PHP errors when you update a plugin, only when you activate it, so it was crashing their sites. The check uses the [PHP_VERSION_ID and PHP_VERSION constants](http://php.net/manual/en/reserved.constants.php), which I thought were reliable ways to test the PHP version (it worked on the 3+ different servers and hosting platforms we tried it on) but it’s possible that is not be the case. * If any of you know how to tinker with PHP, could you try quickly running `` on your site and show me what it outputs, that would help me track down what is going on. * For the time being, I have provided a version of 2.0.2 (which has other important fixes, so you don’t just want to downgrade) without the PHP check here: [http://www.authormedia.com/wp-content/plugins/mbt-api-backend/mybooktable.2.0.2.nocheck.zip](http://www.authormedia.com/wp-content/plugins/mbt-api-backend/mybooktable.2.0.2.nocheck.zip) * [mcshanecomm](https://wordpress.org/support/users/mcshanecomm/) * (@mcshanecomm) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748805) * Thanks, guys! * Here’s the php info on my server: [http://bc.mcshanedev.com/phpinfo.php](http://bc.mcshanedev.com/phpinfo.php) * Does that have all you need? * I’ll download that other 2.0.2 update and see how it goes. * Thank you!! * [mcshanecomm](https://wordpress.org/support/users/mcshanecomm/) * (@mcshanecomm) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748806) * Ha! Well, that shows my control panel is lying about which PHP version it runs, huh? Yikes! * So… will the 2.0.2 even work for me? I’ll wait for further info. * Thanks!! * Plugin Author [zookatron](https://wordpress.org/support/users/zookatron/) * (@zookatron) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748815) * Hmmm, yeah, it might be that some hosting providers are being less than honest about the PHP versions that they are displaying 🙂 * Versions of MyBookTable 2.0.0 and up make use of slightly newer PHP functionality that will crash your site if you have less than PHP 5.3.0, and it is highly recommended that you have at least 5.3.9, which is what we check for in the PHP checker. * ~Tim * [mcshanecomm](https://wordpress.org/support/users/mcshanecomm/) * (@mcshanecomm) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748817) * I see. * Well, unfortunately, I don’t think my host will update the PHP version since my site is on a shared server… I showed our client the site with MBT and he loved it, so I would hate to have to tell him I can’t use it. * Can I download the previous version of the plugin to downgrade to pre-2.0 version? * Thanks! * [KSJones](https://wordpress.org/support/users/ksjones/) * (@ksjones) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748818) * 2.0.2 update changed nothing for me… Still do not have MyBookTable. [http://www.ksjones.com](http://www.ksjones.com) and still have the ‘PHP Out of Date’ reference. * [http://www.ksjones.com](http://www.ksjones.com) * Plugin Author [zookatron](https://wordpress.org/support/users/zookatron/) * (@zookatron) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748819) * [@mcshanecomm](https://wordpress.org/support/users/mcshanecomm/): * I can send you an older version of MyBookTable if you insist, but you must know it will be completely unsupported and that the [Professional and Developer Upgrades](http://www.authormedia.com/products/mybooktable/upgrades/) will not work with it. I’d also highly recommend that you try to get your host to update your PHP, PHP 5.2.17 is over four years old and it is potentially quite dangerous to run such old versions of PHP on public-facing websites. * [@ksjones](https://wordpress.org/support/users/ksjones/): * Have you contacted your hosting provider to verify that your particular website is indeed using PHP 5.3.9 or newer? Newer versions of MyBookTable simply will not work with anything less than PHP 5.3. If you are absolutely sure that you are using a newer version of PHP and that the Out of Date message is in error, please be sure you have removed the old version of MyBookTable 2.0.2 (Note: you must use FTP to remove your old version, do not use the “Delete” link on the WordPress plugins page or it will delete all MyBookTable books, settings, authors, and series from your website) and download and install this special version that removes the PHP check: [http://www.authormedia.com/wp-content/plugins/mbt-api-backend/mybooktable.2.0.2.nocheck.zip](http://www.authormedia.com/wp-content/plugins/mbt-api-backend/mybooktable.2.0.2.nocheck.zip) * [mcshanecomm](https://wordpress.org/support/users/mcshanecomm/) * (@mcshanecomm) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748823) * Tim, Thank you millions for your patience. Turns out, I COULD change the PHP version in the control panel at my host, and I just did that, and the plugin is happy again. Just see I have to tweak the buy button styles. But looks like I’m all set now! * Thank you so much! * Plugin Author [zookatron](https://wordpress.org/support/users/zookatron/) * (@zookatron) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748827) * No problem, I’m glad you got it fixed! 🙂 Let us know if you run into any more problems using MyBookTable, we’re always happy to help. * [KSJones](https://wordpress.org/support/users/ksjones/) * (@ksjones) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748839) * [@zookatron](https://wordpress.org/support/users/zookatron/) Thank you for your help. My hosting provider is GoDaddy. I called and they updated my PHP to 5.4, then said that my site level will be become obsolete in June 2015 anyway! Nice, right? It’s 4-years old. I guess I’ll worry about my site and MyBookTable existence again in June. Oh! And MyBookTable is now back on my site. I just need to rebuild it. * Your assistance is appreciated! * Plugin Author [zookatron](https://wordpress.org/support/users/zookatron/) * (@zookatron) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-53-warning/#post-5748842) * No problem, good to hear everything is working for you again as well.
