**Your software** My Mautic version is: 4.4.4, fresh install from zip file. My PHP version is: 7.4.30 My Database type and version is: mysql Ver 15.1 Distrib 10.5.15-MariaDB, for debian-linux-gnu (x86\_64) Web sever: nginx 1.18.0 **Your problem** My problem is: I removed the cache as sudo user (`sudo rm -rf var/cache/*` which I should not have done). After that the mautic page is down. It is still not working. These errors are showing in the log: ```auto [2022-11-11 13:02:45] mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Filesystem\Exception\IOException: "Cannot rename "/tmp/UrlMatcher.phpIClvgH" to "/var/www/html/mautic/var/cache/prod/UrlMatcher.php"." at /var/www/html/mautic/vendor/symfony/filesystem/Filesystem.php line 290 {"exception":"[object] (Symfony\\Component\\Filesystem\\Exception\\IOException(code: 0): Cannot rename \"/tmp/UrlMatcher.phpIClvgH\" to \"/var/www/html/mautic/var/cache/prod/UrlMatcher.php\". at /var/www/html/mautic/vendor/symfony/filesystem/Filesystem.php:290)"} {"hostname":"vps","pid":32368} [2022-11-11 13:02:45] mautic.NOTICE: PHP Notice - Undefined variable: inline - in file /var/www/html/mautic/offline.php - at line 77 {"inTemplate":true,"isAjax":false,"message":"The site is currently offline due to encountering an error.

I reset the permissons and owner of the mautic directory, clear the cache following this guide [https://docs.mautic.org/en/troubleshooting/file-ownership-and-permissions](https://docs.mautic.org/en/troubleshooting/file-ownership-and-permissions). This time I perform the commands as the user of the web server. Still not working. as www-data, I ran: ```auto find . -type f -not -perm 644 -exec chmod 644 {} + find . -type d -not -perm 755 -exec chmod 755 {} + chmod -R g+w var/cache/ var/logs/ app/config/ chmod -R g+w media/files/ media/images/ translations/ rm -rf var/cache/* ``` as sudo, I ran: sudo chown -R www-data:www-data /path/to/mautic 1. restart php, nginx and the server. it does not help. 2. I think this is related to the permisson, but don’t know what to do more than the link above. Thank you for your support. Cheers. ---

now that your file ownership is fixed, please try `sudo -u www-data php //bin console cache:clear` ---

Thank you @ekke for your quick reply. I did clear the cache that way, again as you suggested. The site is still broken. In between, I see another message coming, maybe due to one of the cronjob that I set. ```auto [2022-11-11 14:26:09] mautic.NOTICE: PHP Notice - SessionHandler::gc(): ps_files_cleanup_dir: opendir(/var/lib/php/sessions) failed: Permission denied (13) - in file /var/www/html/mautic/vendor/symfony/http-foundation/Session/Storage/Handler/StrictSessionHandler.php - at line 106 {"maxlifetime":1440} {"hostname":"vps","pid":1248} ``` ---

Hmm , not sure this is related, it is only a notice (affecting the cleanup) which should not break the system. I would guess it was there before your issues started. So… are we sure your web server is running under the www-data user? ---

I think nginx is running under www-data ```auto sudo ps aux| grep nginx root 984 0.0 0.0 59164 1772 ?

Ok… I keep asking the simple questions, because just deleting var/cache/\* should not cause serious issues: - did you check the Mautic logs, too? (in /var/log) - can you share an ls -lR /var/cache/ ? ---

@ekke you are right. it’s better to start with simple things. the output you asked for are here: [nginx log error](https://pastebin.com/5whSdS6p) and [cache](https://pastebin.com/iVXD33Aa) thank you for your time. ---

Uuuh - Cache files all owned by root! Try another rm -rf /var/cache/\* plus clear cache see above ---

Can you make sure that var/cache does not contain any other files and folder other then: - ip\_data/ - languageList.txt - prod/ - dev/ - run/ Then move one dir up with `cd ..` and run the following: ```auto chown -R www-data:root cache cd cache find . type f -exec chmod 644 {} \; find . type d -exec chmod 755 {} \; ``` and try again. If that does not work can you share what happens when you go to mautic root dir and run (this is only temporary for debugging and should be **addressed differently as its leaving your server exposed** ) ```auto chown -R www-data: . ``` Does it work then? Give it a try and let me know. ---

change group to cache does not work. I am not sure the second command gives what you expected. I don’t see change sin the group, they remain all www-data [see output here](https://pastebin.com/r5JRMicS). I did it any way, after that, the site is still not working (checked on different browsers) Then I checked in var/logs/…php. no more messages after all these commands. Basically I can install another instance from scratch. I don’t have data on this install, but I wish to clarify the problem just in case someone accidentally does what I did to remove the cache. thank you much for your time.
