See FAQ Recommended Hosting for an **ihost-optimised `php.ini` template** you can copy and paste. ### Compatibility * Scheduled posts: applies the correct author at publish time. * REST/remote publishing (for example, MultiPost plugin): ensures the correct author after categories and content are set. * Designed for large editorial teams. ### How It Works 1. Go to **Settings Author by Category** and create rules that match categories to users. 2. When a post is saved or published, the plugin checks which categories are selected. 3. If a matching rule is found, the post author is updated automatically. 4. If an editor changes the author manually, the plugin remembers that choice for future posts with the same categories. ### Privacy This plugin does not collect, store, or share any data. ### Credits Developed by [Unioney](https://unioney.com). ## Screenshots * [[ * Settings page showing Category User(s) mapping. ## Installation 1. Upload the plugin folder to `/wp-content/plugins/`. 2. Activate the plugin from the WordPress dashboard under **Plugins**. 3. Go to **Settings Author by Category** and set up your rules. 4. Drag and reorder rules — the first matching rule applies. ## FAQ ### Can editors still change the author manually? = Yes. Editors can always choose a different author, and the plugin will remember their choice. ### What happens if the post’s categories don’t match any rule? = The author won’t change. The plugin does nothing in that case. ### Can I include more than one category in a rule? = Yes. You can select multiple categories for each rule. ### What happens when publishing from another plugin or remote site? = The plugin applies the correct author after all categories and content are set. ### Does this plugin work with other/custom post types or pages? = No. Currently, it only supports regular blog posts. Support may be added in future releases if there is user demand. ### Will this work on large sites with many users? = Yes. The interface is optimized to work efficiently, even with thousands of users. ### Who can manage the plugin settings? = Administrators have access by default. You can also allow other roles or specific users through the Access Control panel. ### If I have an issue with this plugin, how do I contact you? You can easily contact us by visiting abc@unioney.com and sending us all the details, screenshots, or videos you have on hand so we can try to fix any issue. ### What PHP settings are recommended for best performance on ihost? We run happily on any modern host, but if you want “zero-tuning” speed and reliability we recommend [ihost WordPress Cloud Hosting](https://ihost.eco/wordpress-cloud). **Why ihost works so well with all plugins** * **Web Optimisation:** One-click optimisation suite that minifies HTML, CSS, JS and compresses images automatically. * **Free and unlimited ihostCDN:** A fully featured global CDN (not a slimmed-down plan) for faster delivery everywhere. * **Website Acceleration Suite:** Server-side image resizing, compression, lazy loading, and code minification without extra plugins. * **Edge caching:** Static assets (images, JS, CSS) are cached at ihost’s edge locations worldwide for ultra-low latency. * **Optimised PHP:** Customised PHP-FPM and OPcache; multiple PHP versions (5.6 8.4) available for safe upgrade testing. * **Unlimited hosting:** No artificial limits on the number of WordPress sites— scale up as your server resources allow. * **ihost PHP directives** * `ini asp_tags = 0 auto_append_file = auto_prepend_file = display_errors = 0 error_reporting = 22527 file_uploads = 1 max_execution_time = 300 max_file_uploads = 50 max_input_time = 300 max_input_vars = 10000 memory_limit = 1024M output_buffering = 0 post_max_size = 256M short_open_tag = 1 upload_max_filesize = 256M zlib.output_compression = 0 ## Reviews ![](https://secure.gravatar.com/avatar/a6a26adadfad2b56091b85865f1ec62ecd36bf6d667ad049acc508f716cd68b0? s=60&d=retro&r=g) ### 󠀁[Super useful and lightweight](https://wordpress.org/support/topic/super-useful-and-lightweight-2/)󠁿 [Amanda](https://profiles.wordpress.org/saroco/) September 29, 2025 Super handy plugin!
