PHP errors occasionally after cache clear

Occasionally after a cache clear I get the same two PHP errors at the top of a page:

Warning: include(/var/sites/mysite/public_html/core/cache/includes/elements/modplugin/18.include.cache.php) [function.include]: failed to open stream: No such file or directory in /var/sites/mysite/public_html/core/model/modx/modscript.class.php on line 151

Warning: include() [function.include]: Failed opening '/var/sites/mysite/public_html/core/cache/includes/elements/modplugin/18.include.cache.php' for inclusion (include_path='.:/usr/local/lib/php') in /var/sites/mysite/public_html/core/model/modx/modscript.class.php on line 151

Error in MODX log:

[2013-03-12 17:13:04] (ERROR @ /manager/index.php) The menu cache could not be written.

Has anyone else noticed this behaviour?

Revolution: 2.2.6-pl (traditional)
Mysql: 5.5.28-29.1
PHP: 5.3.10 [ed. note: absent42 last edited this post 13 years, 6 months ago.]

Go to your Elements tab and see which plugin has the ID 18 that is the plugin causing your issues.

Hope that gives you an idea what the real issue is.

Good luck.

Thanks for the tip, I'll do a little more testing.

Disabled that plugin, now it's just going to:

Warning: filemtime() [function.filemtime]: stat failed for /var/sites/mysite/public_html/core/cache/includes/elements/modplugin/19.include.cache.php in /var/sites/mysite/public_html/core/model/modx/modscript.class.php on line 130

[2013-03-12 21:59:48] (ERROR @ /manager/index.php) Error caching script elements/modplugin/19
[2013-03-12 21:59:48] (ERROR @ /manager/index.php) The menu cache could not be written.

Which by your suggestion is now an error with plugin ID 19.

Try clearing all core/cache/ folder contents and make sure the directory is writable for PHP

It's fairly obvious that there's something tripping over itself with the caching subsystem. Even on the Cloud I regularly get errors with the cache files. For example, on my own site just now I find

[2013-03-12 00:46:26] (ERROR @ /index.php) Could not retrieve data to cache for resource 51
[2013-03-12 09:30:55] (ERROR @ /index.php) Could not retrieve data to cache for resource 50
[2013-03-12 09:31:02] (ERROR @ /index.php) Could not retrieve data to cache for resource 52

Hi Susan, did you ever find out the cause of those cache errors? I'm getting this on a few sites after upgrading to 2.5.5
