@e107help Use CDN for core libraries | is on No
PHP 8.3 - standard e107 github 18-08-2026

A lot of repeated warnings under PHP errors on every admin page:

PHP Errors:

Can you see why? with CDN for core libraries = ON there's more:

Is this a problem or can i ignore this for now?

@Alex-e107nl @tgtje Safe to ignore, and nothing on your sites is failing. The panel is showing you a warning that core had already asked PHP to swallow.

The CDN pref is not behind it, and your own report is what rules that out: you saw these with Use CDN for core libraries set to No as well. Each S_Library_* line is one library whose resolution has not been written to the cache yet, and library_manager.php writes it immediately after the miss, so the list changes when you flip the pref and shrinks as the caches fill. Turning it off will not stop the warnings.

The mechanism, since you asked why. cache_handler.php:147 reads a cache file's timestamp with @filemtime(), where the @ means "this may fail and I don't want to hear about it". e107 registers its own error handler, and PHP hands a registered handler every diagnostic whatever the reporting level says, so class2.php collected the warning anyway and printed it under PHP Errors. A cache miss is the ordinary case, which is why it repeats.

It started showing because of a change of ours. That line used to be guarded by file_exists(); PR #5934 replaced the pair with the single suppressed stat to close a race against a cache clear, and the miss path went from silent to noisy.

@tgtje, your two behave differently because only one of them is ever written. S_Config_emote went after Empty Cache because the next page rebuilt it and wrote it back. S_Glyphs_fa6_far has nothing to rebuild from: FontAwesome 6's Regular set is a Pro-only download, so core does not ship its glyph list and getGlyphs() returns early rather than cache an empty result. Every page asks for a file nothing ever writes.

#6038 (master) and #6039 (v2.3.x) propose making the handler honour @, which would take these out of your panel. Nothing is lost by it: the show ALL php errors debug level still shows suppressed diagnostics, so they are a tick box away rather than gone. Whether that is the right shape, and whether it lands, is @Deltik's call. Meanwhile dropping the debug level back to none hides them, and leaving them alone costs you nothing.
