FAQ

                        

                                                            

                                    Does this execute PHP code?
                                    
No. It only analyzes error text locally in the browser.

                                

                                                            

                                    Can it solve every framework error?
                                    
No. It explains common PHP failure families and suggests first checks.

                                

                                                            

                                    What should I include?
                                    
Paste the exact error, file path, line number and the command or request that triggered it.

Class not found errors usually come from autoload configuration, namespace mismatches, missing packages or case-sensitive file paths after deployment.
