There has been an error processing your request. Can't sign in to magento2 admin panel

Dear People, 

 

I tried to install an extension for magento2 from the admin panel and it wasn't able to pass the readiness check. I realised that I had php 7.1 and not 7.2. I removed 7.1 and installed 7.2 and that's where the problem began. Bear in mind that I have magento2 installed on a VPS. I fixed most of the issues, as the Luma frontend is working (except for the search as it gives the following error) and I can also see the admin panel, but once I enter my credentials and press login, it displays:

 

There has been an error processing your request

 

Exception printing is disabled by default for security reasons.

Error log record number: d30f145de40498f5e3d207d31704d784fe721953c222e44dd93beb88cfae3e5f

 

I tried the solutions posted in one of the earlier topics, however, it was all in vain. I checked for the error report under var/report in the magento folder and it was as below:

Re: There has been an error processing your request. Can't sign in to magento2 admin panel

Hi @thomas_jill 

Looks like PHP GD extension is missing.

sudo apt-get install php7.2-gd


Then restart php service once and try.

Also make sure that you have installed all required php extensions. for More info

I hope it will help you!

Re: There has been an error processing your request. Can't sign in to magento2 admin panel

I introduced Magento, signed in administrator board. Be that as it may, in the event that I push on any connect to open let say CMS pages or clients setup, I get mistake this way: There has been a blunder preparing your solicitation Special case printing is handicapped as a matter of course for security reasons. Mistake log record number: 673618173351 That blunder log record number appears as though a connection, however squeezing it nothing occurs. I attempted to search for some log record in magento documents, yet didn't discover any.
