issue with template-builder.class.php

Hi,
We have a issue with our website, SiteGround say :
An average script execution takes more than 40 seconds which is extremely slow and is the reason for the Timeout errors. An average script execution should not take more than 1 second to complete. This means there is a script on your website that is taking too long time to execute (possibly a plugin or the theme).

I have noticed that the scripts were much faster on 2020-03-14 (4 days ago) when they took less than 1 second to execute, hence it seems the issue occurred after that (possibly a plugin/theme was installed/updated or another website-wide change was introduced).

I profiled the loading time of the website with WP Profile tool and it shows these stages are the slowest:

Code:
| stage | time | query_time | query_count | cache_ratio | cache_hits | cache_misses | hook_time | hook_count | request_time | request_count |
+————+———-+————+————-+————-+————+————–+———–+————+————–+—————+
| bootstrap | 28.5841s | 3.6112s | 1209 | 100% | 2479 | 0 | 25.9669s | 12900 | 0s | 0 |
| main_query | 1.1074s | 0.1381s | 46 | 100% | 92 | 0 | 0.8446s | 346 | 0s | 0 |
| template | 31.901s | 4.2945s | 1231 | 100% | 5244 | 0 | 19.8564s | 14421 | 0s | 0 |

The slowest point is:

Code:
AviaBuilder->loadLibraries() | 56.2844s | enfold/config-templatebuilder/avia-template-builder/php/template-builder.class.php:496
| avia_custom_styles() | 15.3856s | enfold/functions.php:681

It seems the slowness comes mainly from the website theme (Enfold). I would recommend you to revise the theme and contact its developers, if necessary so they can check why it loads so slow as it is delaying the website the most. Please note our main focus is on providing hosting-related assistance and troubleshooting issues with the website code (plugins/theme) is not included, but the theme creators should be able to provide insight as to the reason for its slowness.

We need your help, we cant login to wp-admin !
Thanks in advance
