I am not having a good experience with my usual channels so I thought I would come here.
I have a couple of issues I want to address & fix and also some optimization jobs.
FYI:
Opencart 2.3.0.2
Journal 3.1.4
Multimerch 8.11
But I am not looking for any work done on journal just so you know

First: Syntax error invalid token at line 0 I get this only sometimes when I open my admin, it happened only recently in the past couple of days since I moved to a VPS, never experienced it before. It seems to relate to the sales analytics chart and the map, if I refresh it might be normal, might do it again, might not. Mostly it just functions normally. Scratching my head at this one, thinking it might be host related somehow.
Secondly, I have a couple of errors in the error log I wish to fix, none of which seem to be causing any detrimental effect on the site, but alas, want to clean that up, there are only 6 offenders there.
Thirdly, I wish to optimize my DB and add indexes wherever it's possible to speed it up, especially on the front end on Multimerch if a seller is using the reports it can sometimes use up an entire core!
Forth: I wish to do a couple of edits on my header security, mostly okay, scores an A, also running a firewall too, host level and Astra, but regarding headers, one of the policies were changed and id like to reflect that and configure it properly.
Fifth: Ensure my .htaccess is actually configured properly for Gzip, I do not think that it is.
Happy to pay, name a price per fix, or per hour. 1st job I am happy to pay half up front then the second half on a fix, after that I'll be happy to pay upfront there on out.
