By the way, Neos / Flow generates folders like “%FLOW_PATH_DATA%Logs” (root) or “%FLOW_PATH_DATA%Persistent” (Web). They also exist on my local system. Where do they come from? It looks like a variable wasn’t correctly resolved.
That’s very odd and the error message also shows that the variable PHP_BINDIR hasn’t been resolved. Could you please take a look at the file in Data/Temporary/{Context}/Configuration and check if it also includes the variables?
It should for example contain under Neos => Flow => log => systemLogger => backendOptions => logFileURL the value (defined('FLOW_PATH_DATA') ? constant('FLOW_PATH_DATA') : null) . 'Logs/System_Development.log'.
I’d guess your configuration file instead contains '%FLOW_PATH_DATA%Logs/System_Development.log', which would hint at the according replacement pattern not matching. In that case it would be good to know if there is a special encoding in the file or in your source Configuration files, or if anything else looks suspicious.
Okay, that looks indeed correct so far. Can you please check what the output is if you just echo out the result of that constant('FLOW_PATH_DATA') call? Optimally put it somewhere early in the bootstrap.
The FLOW_PATH_DATA seems to be ok. I don’t think that this is a permanently problem. It seems to happen in between sometimes. But I can’t reproduce it, I can’t see that a single command or action is responsible for it. The %-directories are also empty and everything is at the right place. When I delete the %-directories they won’t re-appear immediately.
