Title: Illegal String Offset & Fatal Error Last modified: January 20, 2021 --- # Illegal String Offset & Fatal Error * [hallowelt55](https://wordpress.org/support/users/hallowelt55/) * (@hallowelt55) * [5 years, 4 months ago](https://wordpress.org/support/topic/illegal-string-offset-fatal-error/) * Hi, * just recently, most of my WP Download buttons started to cause the following warning and error: * Warning: Illegal string offset ‘6007e5d7dc0f4’ in /home/…/public_html/wp-content/ plugins/download-manager/libs/class.DownloadStats.php on line 50 * Fatal error: Allowed memory size of 805306368 bytes exhausted (tried to allocate 600700032 bytes) in /home/…/public_html/wp-includes/formatting.php on line 2757 * Any idea what this is caused by?

These include: * **1.Editing the `wp-config.php` file** **2.Editing the `php.ini` file** **3. Editing the `.htaccess` file** * **1.Editing the `wp-config.php` file** * Here you will need to edit the`wp-config.php` file. `define( 'WP_MEMORY_LIMIT',' 1024M' );` * **2.Editing the `php.ini` file** * On a live install, the file can be accessed within the root of your install, that is within the **/public_html/** folder. Note that the file is not installed by WordPress but in most cases set up by your host. If you are using CPanel as your control panel, for example, make sure the checkbox for “Show Hidden Files” is checked and then click Go. You may check into this article on how to go about editing the file. Before editing the file, kindly preserve a backup to it by downloading it to your computer. Once this is done, open the file, add or edit the following line: * `memory_limit 512M` * **3.Editing the `.htaccess` file** * The `.htaccess` file is a file located within the root of your WordPress files. * You will need to add or edit the following code to the bottom of the file: * `php_value memory_limit 256M` * With this done, you can then save your changes and check if the error is resolved. * Thanks * Thread Starter [hallowelt55](https://wordpress.org/support/users/hallowelt55/) * (@hallowelt55) * [5 years, 4 months ago](https://wordpress.org/support/topic/illegal-string-offset-fatal-error/#post-13936162) * Hi, * thanks for the quick response and your suggestions. However, I am wondering if increasing the memory limit is really necessary and a sustainable solution. Can you explain to me what this huge usage of memory is caused by? I mean what action in the whole process of downloading a file (not bigger than 2MB) and updating the stats could use that amount of memory? Just curious. * Thanks in advance * Thread Starter [hallowelt55](https://wordpress.org/support/users/hallowelt55/) * (@hallowelt55) * [5 years, 4 months ago](https://wordpress.org/support/topic/illegal-string-offset-fatal-error/#post-13951498) * Again I am running into these kinds of errors. I am just wondering, why does the plugin try to allocate these enormous file sizes? * Fatal error: Allowed memory size of 805306368 bytes exhausted (tried to allocate 9223372036854775840 bytes) in …public_html/wp-content/plugins/download-manager/ libs/class.DownloadStats.php on line 50 * Please explain it to me. I want to understand it. * Plugin Support [Nayeem Hyder](https://wordpress.org/support/users/nriddhi/) * (@nriddhi) * [5 years, 4 months ago](https://wordpress.org/support/topic/illegal-string-offset-fatal-error/#post-13951529) * Has the problem been resolved? * WordPress is written in `PHP`, which is a server-side programming language. Every website needs a WordPress hosting server for it to function properly. * Web servers are just like any other computer. They need memory to efficiently run multiple applications at the same time. Server administrators allocate specific memory size to different applications including PHP. * When your WordPress code requires more memory than the default allocated memory, you get to see this error. * I hope you have understood * Thanks * Thread Starter [hallowelt55](https://wordpress.org/support/users/hallowelt55/) * (@hallowelt55) * [5 years, 4 months ago](https://wordpress.org/support/topic/illegal-string-offset-fatal-error/#post-13951834) * No, the problem has not been resolved. * I checked with my hosting provider and php memory limit for my site is already set to a max of over 700MB. So the problem has to be related to the plugin. * If you read my last message in detail, you see that error message says it tried to allocate 9223372036854775840 bytes, that’s like 9223372036 GB. Doesn’t that look suspicious to you in any way? * I also figured out, the underlying link for the download looks something like this: …/download/filename/?wpdmdl=14854&refresh=600e7752606f81611560786 * The download of the file works when I remove the ‘refresh’ argument. Still shows the error but at least starts the download. I think it has to be some issue with the stats tracking. * I should also mention, that everything works totally fine when I am logged into my WordPress backend. Only causes these warnings and errors when accessing from the outside like a normal visitor. * Btw, thanks for taking the time to responding to my questions. I know you only try to help, I just need to figure out the root of the issue. - This reply was modified 5 years, 4 months ago by [hallowelt55](https://wordpress.org/support/users/hallowelt55/). - This reply was modified 5 years, 4 months ago by [hallowelt55](https://wordpress.org/support/users/hallowelt55/). - This reply was modified 5 years, 4 months ago by [hallowelt55](https://wordpress.org/support/users/hallowelt55/). - This reply was modified 5 years, 4 months ago by [hallowelt55](https://wordpress.org/support/users/hallowelt55/). - This reply was modified 5 years, 4 months ago by [hallowelt55](https://wordpress.org/support/users/hallowelt55/). * Plugin Support [Nayeem Hyder](https://wordpress.org/support/users/nriddhi/) * (@nriddhi) * [5 years, 4 months ago](https://wordpress.org/support/topic/illegal-string-offset-fatal-error/#post-13952042) * Are you PRO user or free, if possible, share the related file/package URL * thanks * Thread Starter [hallowelt55](https://wordpress.org/support/users/hallowelt55/) * (@hallowelt55) * [5 years, 4 months ago](https://wordpress.org/support/topic/illegal-string-offset-fatal-error/#post-13952119) * Currently a free user.
