After updating, blank page opens even though I write the information on config.php again

I have a problem. PKP Compenent was not installing. I also updated to the new version. This time, the image in the picture occurred. Every time I enter the data in the index.php / index / install page, a blank page is opened every time. I have restored again. This time he started to give an error in the form “Warning: Creating default object from empty value in /home/ejderhub/public_html/cache/t_compile/00a0a0910209607cb33eb0fe6474f30ed7399ed7^52019e87b90081f2c6bfa717994d81ab7712dd1f_0.phend”
