We’ve gone from two files in wp-content/uploads/hummingbird-assets/ about an hour ago to xxx files right now, and the number is continuing to grow. * We originally had this problem with Hummingbird 3.5.0 and disabled the plugin until we could investigate. But then Hummingbird 3.6.0 came out, we upgraded, and everything worked fine for over two weeks, until we encountered the problem again and posted here in the forums. So although everything is looking better right now, we’re going to wait until the end of the month before considering the issue resolved on our end. Feel free to close this forum post in the meantime, if you like. * Thanks again for your time and work in taking a look at this for us and flagging FS_METHOD being set to ssh2 as an issue and suggesting that we reset Hummingbird Asset Optimization. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Hummingbird Performance - Cache & Page Speed Optimization for Core Web Vitals | Critical CSS | Minify CSS | Defer CSS Javascript | CDN] PHP memory limit error](https://wordpress.org/support/topic/php-memory-limit-error/) * Thread Starter [markmont](https://wordpress.org/support/users/markmont/) * (@markmont) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-memory-limit-error/#post-17181261) * Hi, Adam — thanks for the very helpful reply. You are correct that the wp-content folder is not writable for security reasons, but within that folder, the uploads, wphb-cache, and wphb-logs folders are writable and within the uploads folder, the hummingbird-assets folder is also writable (114291149 below is the user ID that the web server runs as). The timestamp on the directory is from when we briefly re-enabled Hummingbird for testing yesterday, showing that Hummingbird did something there, but there are only two files in the directory (I expected many more) and the files were created more than a month ago. * ```wp-block-code $ pwd /.../web/wp-content $ ls -ld uploads/hummingbird-assets/ drwxr-xr-x. 2 114291149 apache 421888 Nov 6 12:36 uploads/hummingbird-assets/ $ ls -l uploads/hummingbird-assets/ total 161 -rw-r--r--. 1 114291149 apache 59152 Oct 6 12:58 0af8e64a2b79d2097b64333c762b8ad1.css -rw-r--r--. 1 114291149 apache 104516 Oct 6 12:58 a0b6bdbec23ca11530095bba8b645ba2.css $ ``` * When investigating today, I found that the total size of the website is 26 GB and there is only 3.6 GB space remaining in the filesystem quota. Just in case Hummingbird was trying to generate more than 3 GB of assets, I’m having the filesystem quota increased today (25 additional GB of space added, to give us 28 GB free space), we’ll reactivate Hummingbird, reset Asset Optimization, and then we’ll re-test things. We have not seen any out of disk space errors, though — just PHP memory limit exceeded errors. * FS_METHOD is set to ‘ssh2′ in wp-config.php. There are no credentials in that file, database, or elsewhere — the ssh-sftp-updater-support plugin prompts for credentials when updating plugins and themes (wp-content and the plugin and themes sub-folders are not writable by the web server for security reasons). Since we only need this for updating WordPress core, plugins, and themes (and we don’t need to do those things right now), we’ll comment out this line in wp-config. php so that WordPress’ get_filesystem_method function will return ‘direct’, and see if that helps. * Here are responses for the other things you listed: - _conflicts with other JS/CSS optimization tools/features (e.g. other similar plugisn) on site_ — there are no other optimization plugins installed. We did originally use WP Fastest Cache before we switched to Hummingbird, but WP Fastested cache was deactivated and removed. - _some unusual or misconfigured page builder_ — there is no page builder (such as Divi or Elementor) installed. We’re using Gutenberg. - _issues (related to access permissions or conflict with other plugins) with correct handling of data in DB_ — we’ll see if increasing disk quota, commenting out the FS_METHOD define, and resetting Hummingbird Asset Optimization fixes things. I’m not aware of any plugins that would conflict (you have a list from our Site Health report), but I’ll keep an eye out for the possibility and we may try temporarily disabling other plugins to see if the problem goes away. - _incorrectly functioning cron or action scheduler_ — `wp cron test` returns“ Success: WP-Cron spawning is working as expected.” and things such as version checks, upgrade checks, and expired transient deletions are all things we have observed to be working. - _sometimes it may also be due to server-side cache that’s either malfunctioning or not fully/properly integrated with site itself_ — the only server-side cache is Hummingbird itself (no Varnish, no Redis or other object cache, and no other page cache plugin) although we do have the Cloudflare integration for Hummingbird configured and the site is behind Cloudflare. * To summarize, our plan for right now is to do the following later today: 1. Increase the disk quota substantially (add another 25 GB space so there will be 28 GB free space in total) 2. Temporarily comment out the FS_METHOD define in wp-config.php 3. Reactivate Hummingbird 4. Reset Hummingbird Asset Optimization 5. See if the problem happens again * If I missed anything, got something wrong, or there is something else you can think of, please let me know. Thanks again for all your help on this, we really appreciate it! * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Hummingbird Performance - Cache & Page Speed Optimization for Core Web Vitals | Critical CSS | Minify CSS | Defer CSS Javascript | CDN] PHP memory limit error](https://wordpress.org/support/topic/php-memory-limit-error/) * Thread Starter [markmont](https://wordpress.org/support/users/markmont/) * (@markmont) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-memory-limit-error/#post-17179349) * Hi, Patrick, thanks for your help! * Hummingbird > Assets Optimization shows 28,635 assets.

Patrick! I will get this information from the website owner and post it here. It won’t be until later this week since they currently have Hummingbird deactivated — I’ll need to arrange a low-traffic time with them to re-activate the plugin and get this information. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[WP DB Driver] PHP Notice: Undefined property: wpdb_drivers::$real_escape](https://wordpress.org/support/topic/php-notice-undefined-property-wpdb_driversreal_escape/) * [markmont](https://wordpress.org/support/users/markmont/) * (@markmont) * [13 years ago](https://wordpress.org/support/topic/php-notice-undefined-property-wpdb_driversreal_escape/#post-3941910) * This is still an issue with plugin version 1.3 when running WP 3.6-RC2 (which was released three days ago). Updating the plugin to the version in GitHub fixed the problem, without any changes to WP 3.6-RC2. Viewing 5 replies - 1 through 5 (of 5 total)
