convertPathToRelative is called to convert each element in the $params array, however only "default" parameter contains file path. There are made excessive convertPathToRelative calls for some parameters (quality, output_format, etc.)

After clean install
Part 4.9 - confirm that you'll see an error message above the system settings list indicating which folders weren't deleted as part of the system setting change. - There appears only "Please manually delete paths:" message. No folder names are present in the message.

Restored chages in the TemplatesCache class, that were accidentally removed.

Corrected permissions on the system folder itself. Report indirect compiled template removal as part of system setting change.

2. \NParserCompiler::FindTemplateFiles - recompile all templates from the System Tools section - first convertPathToRelative call is with $path = /core/admin_templates parameter, so no comversion happens - incoming path already is relative. However, result is relative path, so test is passed.

Reverted change from array_merge into += during template parser mass-compilation error displaying.

Added color names in comments.

Improve handling of log levels, that doesn't require coloring.

All task-defined coloring is right.

"use the above-created user and products (several with different quantities)"

Cosmetic change.

Without this change - also no SQL error. Maybe, because no MySQL 8.x in the test system.

failed parts 1.10, 1.11. (in both clean install and upgrade cases)

after "use the Clear Templates Cache functionality"
system/cache/core/admin_templates folder is present and has drwxr-xr-x permissions, but system/cache/core/admin_templates/config folder is not present, and system/cache/core/admin_templates/config/config_universal.php file is not present.

under system/cache/core/admin_templates folder are present only incs folder and and tools folder

after "Compiled Template Permission Mode" is changed, system/cache/core/admin_templates/tools folder disappears and system/cache/core/admin_templates/config folder is created, so all other test plan checks are passed.
