Recently I started using open source version of EspoCRM(Version 5.7.11) and it was all working fine. But recently some interfaces are not being loaded(Customers records table/grid view, Create new customer view, Edit customer view, Portal user edit view etc.).
When a view is not being loaded, it shows following error in the browser console[attachment].
"Failed to load resource: the server responded with a status of 409"
"Uncaught Error: Could not load file 'client/modules/crm/src/views/contact/fields/accounts.js?r=1581325536'"
I found that 409 Conflicts are most likely to occur in response to a PUT request. For example, you may get a 409 response when uploading a file which is older than the one already on the server resulting in a version control conflict. But in my case this is a GET request which is trying to access a javascript file.
This occurs only on certain computers while on some other computers, these 409 errors are not present and my EspoCRM instance is working fine.
I tried clearing cache and rebuilding options inside EspoCRM. But no luck.
Files that are returning 409 error have 644 permission and folders have 755 permission. Any idea on what is causing HTTP 409 error?
P.S. Why am I asking this question here and not in EspoCRM support forum? Because I already did and nobody responded so far. So really appreciate if you could shed some light on this.
